Ignorant position.
If you are gay and refused service, you were forced to leave a public accommodation.
See the stupidity and ignorance of your argument with, "If you're black and refused service as such were you FORCED to patronize that business by the business owner to begin with?"
OK legal scholars....put on your thinking caps here. If a Christian walked into (targeted on purpose for the means to exploit a political agenda by filing a lawsuit) a gay billboard designer, open to the public, and asked that billboard designer to print a sign to be placed by multiple major thoroughfares that said "Homosexuality is a sin unto God", if that billboard designer refused, could he be sued by the Christian for discriminating against Christians and refusing them public accommodation?
I am of the opinion that this exact thing should happen. We need to show the world how PA laws are a two-way street and one's sexual-orientation cannot be more legally important than one's religious-orientation. Discrimination is discrimination...
