If success spoils TransAfrica, it won't be Randall Robinson's fault. Marking the 10th anniversary of the black foreign policy lobbying group, the executive director sounded more irked than pleased.

"We are not going to take it anymore!" Robinson vowed in a speech Saturday night to supporters at the Washington Hilton, "it" being the political practice of taking blacks for granted.

While TransAfrica recently won a stunning victory in Congress on South African sanctions, boasts a staff of 15, has raised nearly a million dollars for an endowment and is looking to buy its own office building (forcing even Robinson to admit, "We are no longer an organization -- we are an institution"), there was little evidence of institutional complacency at the gala dinner. It attracted 1,400, including singer Harry Belafonte and Rep. William Gray (D-Pa.), but some weren't in a particularly gala mood.

"This nation and this nation's policy," Robinson thundered, "is stained through and through with racism."

Gray, chairman of the House Budget Committee, seemed to agree.

"The same people who support constructive engagement abroad oppose affirmative action at home," he said in his speech, referring to "old what's-his-name at 1600 Pennsylvania Avenue." Gray noted that 8,000 black children are currently being held in South African jails. "If there were 8,000 children in Polish jails, in Soviet jails, this president would be tripping all over himself to light candles," he said.

Robinson, for his part, attacked the current crop of presidential aspirants, most of whom declined to appear at TransAfrica's foreign policy forum on Friday. He started off with Sen. Bob Dole (R-Kan.), whom Robinson quoted as having called him "a big-lipped Democrat." (Dole's office has insisted that the senator had said "big-lib," as in "liberal.")

"I am neither a Democrat nor a Republican," Robinson declared. "I am a black man."

As if to underscore the point, his next target was Rep. Richard Gephardt (D-Mo.), who recently "called a meeting of 'the blacks,' " according to Robinson.

"He invited 75 of 'the blacks' to discuss little of nothing in little or no time ... The Democratic party cannot win a national election without our support ... This time, brothers and sisters, we ain't giving our support for a handshake and a photo opportunity. It is time for the quid pro quo. If they expect us to take them seriously, at long last they must come to understand that they must take us seriously."

Robinson pointed out that only one candidate came to TransAfrica's symposium -- "the front-runner, Jesse Jackson!" This got lusty applause.

The dinner was emceed by Belafonte, a TransAfrica board member, who outlined the group's agenda: pressing for global sanctions against South Africa and for more U.S. foreign aid to Africa and the Caribbean. He called on the United States to push South Africa to remove its troops from Namibia, adding, in his trademark rasp, that "there should be no linkage to the withdrawal of Cuban troops." He also touted a new campaign called "Faces Behind Apartheid," in which the group is buying full-page newspaper ads against Robert Dole, Sen. Jesse Helms (R-N.C.) and Frank Sinatra -- "whose actions," Belafonte said, "have aided apartheid."

Gray vowed to push for congressional legislation mandating total disinvestment in South Africa and condemned the distribution of American foreign aid, noting that African nations receive only 96 cents per capita while $700 per capita goes to "another region" -- by which everyone understood he meant Israel. "We must end this inequity," Gray said.

At one point he introduced former U.S. representative Charles Diggs (D-Mich.), easily spotted in an ice cream suit as he stood up at his table and waved. Diggs, who served nine months of a three-year prison term arising from a 1978 conviction for a kickback scheme, was a guiding spirit when TransAfrica was born out of the Congressional Black Caucus.

Before the dinner, Belafonte talked of South Africa's inevitable "internal collapse" and "the holocaust that will come."

"I don't believe that those people are without some sort of genetic deficiency," he said of the hard-line Afrikaners. "They will go to any extreme that is necessary, I think ... It's so totally ingrained in their way of life, they're able to do so much without any concern for the moral implications."

He predicted that the outlawed African National Congress would eventually prevail. "All we can hope is to achieve the result with the least loss of life possible."

Belafonte, who once flirted with the idea of running for the Senate from New York, said he didn't know if he would support Jesse Jackson for president. He had been for New York Gov. Mario Cuomo until the latter took himself out of contention. "I was so sure that he would have understood the public will, the public desire," Belafonte said of Cuomo. "I know he understands the national need."

Of Paul Simon's controversial "Graceland" album, he said, "I love it." Simon has received much criticism for recording it with black musicians in South Africa -- a violation, some have said, of a ban against performing there. "I have problems with the methodology," Belafonte said, "but I welcome what he's done."

Also in the crowd was Rep. George Crockett (D-Mich.), chairman of the House subcommittee on Western Hemisphere affairs.

"The clock is ticking for Brother Abrams," Crockett said, referring to Elliott Abrams, assistant secretary of state for inter-American affairs, whom many in Congress have been urging to resign. "I call everyone 'Brother,' " he added. "He had the same attitude {testifying before the Iran-contra committees last week} that he always has. He was extremely cocky, sure of himself, and seemed to have the feeling that everybody else is dumb except Elliott."

Crockett decried the granting of limited immunity to Lt. Col. Oliver North. "I think we got enough on North to hang him without hearing his testimony."

Gray, who supported Jackson for president in 1984, said he is keeping his options open so far. "I haven't made a commitment for any candidate this time," he said. Jackson's front-runner status, he said, is more a reflection of name recognition than political support -- "I don't pay much attention to these early polls" -- but added that Jackson has a chance. "I don't think any candidate is out of the race."

Pop singer Jeffrey Osborne entertained, diving into the crowd to make various dignitaries sing "Woo-woo-woo," the refrain of his hit tune "You Should Be Mine." Although there was a seat for him at the head table, one dignitary, Washington Mayor Marion Barry, didn't show up. "Probably because he knew you were going to be here," Robinson joked to a reporter.

TransAfrica board chairman Richard Hatcher, who recently lost his reelection bid for a fifth term as mayor of Gary, Ind., presented the $1,000 Paul Robeson Prize for an essay on foreign policy to Kimberly Adams, a senior from Wayland High School in Massachusetts. Longtime Washington journalist Ethel Payne received the African Freedom Award.
