Having said that, here is a take from Franklin Graham that indicates maybe the Kleins didn't quite apply the scripture correctly... "In fact, it may surprise some to learn that I think every business should be gay-friendly. By that I mean businesses — like individuals — should be friendly to everyone, customers and citizens, even if or when we disagree with them." If you don't like it, take it up with Franklin.
what the lesson for business is that queers sue. it doesn’t matter for what.
dealing with queers is likely to produce a law suit regardless of what you do
