Sometimes I feel like here is the only place I can be open and proud

I feel like in my life I don't have very many opportunities to be myself and be okay with who I am. I just don't have places like this where I feel comfortable being open and okay with everything.I thought about going to an LGBT young adults group near me, but a gay friend of mine said that he thought that groups like that should be "reserved for gays". Naturally I didn't feel too welcome going there, and have yet to go.Among many of my straight friends, one of two things would happen. Either they'd have the "we get it, you're gay" attitude(phrased based on that wonderful video posted here recently that I plan on sharing), or the "but you're only bi". Yes, I was told that before.I'm either too gay or not gay enough.So at the end of the day my day-to-day life gets exhausting. Invalidated or judged. One of the two.Then I get on /r/ainbow and /r/bisexual and feel so welcomed. Not going to be told to pick a side, not feeling invalidated from all ends, and feeling like I can be myself. I can put that pride flag next to my name happily, but I feel like I can't do that offline.
