After reading about the neighborhood bar that was ruled against in a discrimination suit (LGBT...), similar to this bakery, transitioning to private clubs/organizations may be the only path forward. They can qualify members by their choosing and ban whomever they want.
Otherwise, one could put a sign up the reads “proceeds from sales to the LGBT community will go to x conversion therapy center.”
I guess it could be a solution. But on the other hand, having to resort to this, if this is indeed what has become of freedom in America, what’s really the point of America continuing to exist?
