This is straight up bad logic. Not according to me, but objectively.
f you ever take a debate or philosophy class, this is all covered. Using good reasoning will make your discussions more engaging. I highly recommend checking out something like this:

I don't know if you're really young, or just haven't spent much time in debate, philosophy, whatever, but we're shouting across a canyon, here. I wanted to discuss the case, and you're stuck on saying this person was misgendered without any evidence. I really, really shouldn't have to walk you through why a single uncorroborated statement should be met with skepticism. You're using backwards logic.
That being said, again, I'm not trying to make you feel bad - we're always learning. I am making an effort to show you that you have resources to help you use reason, so that you can make stronger arguments. Otherwise, you're not going to effectively reason what you think or why you think it.
EDIT: And no, I'm not going to walk through, sentence by sentence, breaking down the bad logic. It would literally take up too much of my time. I do urge you to read up on this yourself. Teach a man to fish, and feed him for a lifetime, and all that.
