But in doing that, it also creates the problem you're experiencing of your round peg not fitting either square A or square B's holes, and it doesn't make your viewpoint or experiences any less valid than A's or B's--"privileged" or "minority".

Yes.

This is pretty much the crux of the problem. There's this issue of trying to fit people and experiences into square holes. And that's hard, because we're dealing with people and experiences, and those are always different. But those of us who only have round pegs while everyone else has square ones just feel a bit left out. Because, overall, there are a lot more square pegs than round ones. And sometimes, we can sort of shove that round peg into a square hole, but it doesn't really fit that well. But hey, it's a hole.

And now I might be beating that analogy to death, so I'll stop.

As for acknowledging the issue without dismissing those who don't fit in either or fit in both categories, well, that's the problem when we're talking about people, not numbers or things. It's very weird, because the scientist in me would love to just be able to stick labels on things and go from there, but the confused kid in me knows that's not possible. If that makes any sense whatsoever.
