You can make a libertarian argument for repealing anti discrimination law. It goes like: owners of businesses should have ultimate control over who they do and do not serve. The government should not be forcing them to serve any group of people they don’t want to.

That doesn’t mean you should be screaming it from the rooftops though, or that it’s an effective strategy to get people to take their cause seriously.

If a private business wants to refuse service to people based on the color of their skin or gender or sexuality or what have you, and the community does not like the business because of this, it is likely that business will fail.

There is no better (true) judge of a community's morals and values than the way they spend their money. 

Also, why would I want to force a business to serve me? If they don't like "my kind" there, why would I give them my money?
