Absolutely! Solidarity is key.

Also, sexuality often being defined not just by who you are attracted to but also who you are means that many straight trans people might have thought of themself as gay before they realized they were trans, or others might perceive them as being a gay person, or they themselves might have unresolved feelings about their sexuality still. It can get complicated

I like some of the new terms trying to make sexuality only about who you are attracted to. Makes way more sense imo

Edit: I say this because it came to mind when you said that most of us are LGB, but in many ways we are even more tied up with the LGB than we might first think
