Bisexual Rant

My best friend is a lesbian. I'm bisexual and I lean more towards women. We've been best friends for about 11 years now. A few years ago I accidentally introduced her to her now wife. I can not stand her. She's rude and obnoxious for a lot of reasons, but the most annoying thing she does is act like my issues aren't valid because I am bisexual. Like if I say anything about dating girls she'll say something along the lines of "You're not really gay though." I know A LOT of people that do this, and let me just point out how rude it is. Bisexual people go through the same shit that the rest of the LGBTQ+ community does. But we have the people in this community discriminating against us too. If one more person tells me to basically "pick a side" I'm going to lose my mind.
