Yeah, levers of power. You know, discrimination lawsuits? Where the loser has the government come and confiscate their property by force and give it to the winner? Surely you've heard of those. They've been going on quite a while now.

That would be the liberal way to go, not libertarian. Libertarians believe in freedom of assocition, especially for business owners and consumers, and so do conservatives.
Do you want to make it illegal for lesbians to buy wedding dresses? What if the store owner wants to sell her a wedding dress? What if a lesbian wants to buy a wedding dress for a Halloween costume?
