If someone thinks a bisexual being in a straight relationship suddenly means they're straight, or that it's somehow "bi-erasure"... that's very much a them problem. For normal people, that's blatantly obvious, and we really don't need to be beat over the head with it. The ones that complain about such things tend to be an extremely loud and obnoxious minority, (and as I mentioned previously) fighting on behalf of people who never asked. They also tend to be the same people who (hypocritically) insist bisexuals are just "in the closet", and that bisexuals should "pick a side"... when that's, uh, not how that works. It's in the name; "bi", meaning two, or both.
As an aside, I'm sorry, but respectfully, pansexual isn't a thing—it's lit just bisexual with extra, imaginary steps. Likewise, biromantic+asexual? You realise it's normal for women to have a lower sex drive than men, right? Doesn't suddenly make it a new sexuality. I'm under no delusions that I can convince you of anything, but given this is a public website, I'll speak my piece regardless.
Anyway, the same argument goes for the race example. What you mentioned is very much an American problem since they started this nonsense, fabricating issues where they haven't existed in years. Most of us don't care, and treat everyone the same way. It's really tiring seeing American politics shoehorned into everything, with other Western countries being expected to follow suit. Yeah, no thanks. There's a reason recent games like Concord, Dragon Age: Veilguard, Avowed, and so on, have been complete flops. People are tired of being preached to over problems the "activists" created themselves.
I'd suggest looking up people on Youtube like Amir Odom, Brad Plumbo, Ariel Scarcella, Buck Angel and Marcus Dibb, to name a few. Most of them are American and gay or trans, and speak against all this divisive nonsense being pushed.
Again, good luck on your KS, but just as you can make whatever you like, I can spend my money elsewhere.
