STAN PARRIS may be too busy these days finding new ways to manipulate the local affairs of the District of Columbia, but he should pause at least long enough to accept recognition as champion congressional weight-thrower in D.C. The Virginia congressman's energetic assertions of command over this city have encouraged a new era of District-bashing on Capitol Hill that goes well beyond mere political sport. The chilling effect on a local government already under intense federal investigative scrutiny is considerable. Worse still, there appears to be no end in sight; Mr. Parris and colleagues are just getting into the spirit of things, and the breadth of interests appears to be expanding ominously.

Prisons: Warden-apparent Parris introduces bill to repeal legislation passed by the D.C. Council to ease overcrowding at Lorton Reformatory, which was enacted in response to a court order. In the Senate, Tom Harkin of Iowa, chairman of the Appropriations subcommittee on the District, pushes through a measure to postpone construction of a new city prison because he and residents who have gone over the heads of city hall to Congress don't like the site. Sen. Harkin's predecessor as chairman, Sen. Arlen Specter of Pennsylvania, warns that delay could jeopardize the whole project, a four-year effort that he had spearheaded in cooperation with the city administration.

Abortion: Sen. Don Nickles of Oklahoma tries -- unsuccessfully -- to push through a strict anti-abortion measure preventing use of local revenues (as well as federal funds) to pay for abortions for the poor except to save the life of the mother. In the House, Rep. Robert Dornan of California does the same thing, as he has before. These moves also enjoy the formal support of President Reagan.

AIDS and Insurance: Sen. Jesse Helms of North Carolina seeks to overturn a D.C. insurance law with a measure that would freeze all city funds -- for police, fire and any city services -- unless the D.C. Council agrees to rescind a law prohibiting insurers from requiring tests for AIDS.

Access Road Project: Seven senators, responding to complaints from Wisconsin Avenue Corridor residents unhappy with a local decision, write to the mayor to inform him that they "strongly oppose the city government's decision" to build an access road through the entrance to a park. They urge that the land be transferred to the federal government.

Residency Requirements: Sen. Barbara Mikulski of Maryland, while acknowledging sensitivity "to the principle of home rule," introduces a measure urging the mayor and the council to examine "reasonable alternatives." She emphasizes that the measure does not order the city to change things, but hopes the city "takes the Appropriations Committee's encouragement to heart."

And what about home rule, local self-government or whatever members of Congress like to extol when it comes to localities in their states: Overseer Parris offered some advice in May for any D.C. residents who may be miffed that they lack full representation in Congress. "I'd say buy a house in Alexandria. Love to have you. Or in Silver Spring. I don't care, whatever. That's not the issue. It's not just the rights of the 600,000 people in the District. How about the rights of the 220 million Americans that call this place the Nation's Capital? . . . I think it's a trade-off, if you will, of whose rights are superior."

That's some trade-off -- but for now, it clarifies the inferior position of those Americans who won't or can't move: they're going to be put in their place.
