Gay cruises were originally set up as meat-market orgies on the high seas. Segregation in that case, I believe, everyone supports.
But Family-Friendly gay travel agencies? The only rational reason I see to support this would be to support a gay business. But that's stretching it.
I expect more of this sort of foolishness in the next couple years, with the recent inroads involving the SCOTUS decision and our friends to the north. Stupidity crosses all barriers, after all, and those rulings will be all the excuse some people need to go as far overboard as they can possibly go.
