The Washingtonian explains the intricacies of the DC Human Rights Act:
“The DC Human Rights Act prevents businesses from discriminating against people for their political affiliation (as well as gender, race, religion, etc). “But fringe ideological groups are not political affiliations, as that term’s defined in the [DC] Code,” says Veritas Law attorney Scott Rome, who also spoke on the topic at a pre-inaugural safety training seminar hosted by the Restaurant Association Metropolitan Washington earlier this week. That means restaurants can’t turn away customers for being Republicans, or Trump supporters, but they’d be within their rights to deny service to, say, a group of white nationalists. …”
If you are a White Nationalist going to DC for the Trump Inauguration, remember that ‘civil rights’ doesn’t apply to you as a member of the Untouchables caste. You’re a ‘fringe ideological group’ which means you don’t have a ‘political affiliation’. Personally, I don’t have any objection to this in principle. I would like to see Katzenbach v. McLung overturned. If we are going to have segregation though, everyone should be allowed to do it.
