[Ethan Clive Osgoode]

Find a gay tee shirt printer. Order tee shirts that say “Mankind shall not lie down with mankind as with womankind.” See what he does. If he refuses, sue him.

You will lose the case and probably end up impoverished or imprisoned.

So I repeat charge the gays triple the cost of the printing. In effect they will not be denied or refused services but just billed more for it.
The gay customer can either accept or refuse based on cost. That would change the tactics and open up another can of worms on a different level but rather than purely morals based it becomes an economic freedoms choice. Lets have that argument-—its all fluxed up anyway so why not?
