you need to get that chip off your shoulder, yopu'll feel a lot better for it. Just be gay and be saitisfied, is that too difficult to do? If you encounter someone who is not gay-friendly so what? Plenty of gays these days are not particularly straight- friendly either but we dont make a song and dance about it. You have your Gay pride rallies all over the world, can you imagine the hell that would be unleashed if someone organised a Straight & Proud rally? Through the middle of one of the major cities and affected traffic?
Just get on with being whatever you are for christs sake. Others dont have to approve, it isn't compulsory to approve it you know! Grow up.
