Neither black leaders nor black people, per se, are the prevalent political problem for the Republican Party, as was suggested by Eddie N. Williams ("Black Republicans: Poor Tactics," op-ed, Dec. 16). Rather, the problem is black political operatives and candidates who appeal almost exclusively to emotion, in place of a reasoned, balanced response to the candidates and the issues.

This is not a black phenomenon. Many emerging white ethnic minorities experienced the same type of superficial, self- centered manipulation as they moved toward political assimilation. Fortunately, many whites who previously voted a straight Democratic ticket, such as blue- collar workers and members of organized labor, have awakened to the fact that they do better by thinking for themselves and exercising a healthy political independence.

Black Republicans understand that what's good for America is good for blacks. And President Reagan has been very good for this country. The United States has enjoyed 23 straight months of economic growth. More than 6 million jobs have been created through sustained expansion with low inflation. During 12 of the last 16 years, Republicans have controlled the White House. And during those years, black Americans have made substantial gains.

By understanding the process of power, by becoming a force within the GOP, blacks will be in a position to further help themselves -- to ensure more black appointments to federal positions, to gain support for responsive legislation, to increase the number and size of federal contracts for black businesses.

The Republican Party has demonstrated decisively that it subscribes to the philosophy of "a hand up, not a hand-out." Millions of black Americans support this philosophy. It is now time for them to stand up and be counted within the Republican Party.
