What sort of a loser is it that hates a song because another group of people use it to celebrate their fundamental rights as human beings? Don't bother coming out (ha!) of your cave if that's how you feel about the modern world.
I don't think it's a case of any 'original meaning' having been hijacked - it was always intended to have that gay anthem/personal affirmation double meaning. That's a very Chic thing. Just listen to Nile Rodgers' many interviews on the subject.
