Points where I agree with you:

• It's unfair for bisexuals to demand that they be allowed in communities that are exclusively homosexual, e.g. for gay men.

• The examples you cited were homophobic.

• Yes there's a similar phenomenon going on in lesbian spaces.

Points I think you're missing:

• All of the examples you cited are also TRAs. I think it's worth pointing out that homophobic behavior/beliefs are generalizable to the ideology, but not necessarily to all bisexuals.

I agree with a lot of what you're saying, BUT! You did generalize about "all bisexuals" in some of your comments. (I didn't see that in your actual post, though.) Examples:

• "You don't get to scream "eRaSuRe!" when it suits your whims and then basically call for it yourselves, just because you want to be included in other letter's spaces." Many bisexuals don't do that (and the guy you responded to is not even bisexual).

• "You have – and this time I mean all of bisexuals, apparently – very similar mentality to Ts in department of making yourself the victims, even when we're discussing part of your community doing something shitty." Ironically, I am not bisexual either, lol.

Your frustration with the situation you described is legitimate, and I think your message is too-- that gay men (and lesbians) SHOULD be able to have their own separate communities, if they want. That isn't said enough on Reddit; we get banned for saying that on Reddit. However, I think your message is being missed by some people because of some generalizations you made.

edit: Also, I'm not sure if you knew but some of the people on that thread were reacting more to a troll user who hates bisexual and has made like 10+ accounts that have gotten banned from this sub. His vitriolic comments probably did not help facilitate reasonable discussion, and also distracted from the point of your post.
