If gender is not sex than gender is not real, you can be whatever you want whenever you want, right?

How does "you can chose" make something not real? Also, it doesn't appear to be a conscious effort to be trans. Do you really think trans people go through all that just for the fun of it?

Still, if a dudes is a dude it's a he, if a woman is a woman it's a she.

And if a women is not a woman and starts HRT and everything, he's a dude. You're exactly right!

The only time I would actually bother ask someone what they like to be called is if they have an intersex condition. That's it.

Can you tell that just by looking at people?

Yes, it was the exactly stereotypical "call me mam" hairy dude.

What if it was someone who visually fit in your expectation? Would you treat them with basic respect? Can you tell me the sex of each of those people?

No but I would love too, that seems genuinely interesting. I'd have so many questions to ask

Wouldn't it be interesting to talk to a trans person, too? Understand their perspective? Maybe you already met someone intersex but called them slurs and walked off because you thought they might be trans.

Your baseless hate for trans people only brings evil into this world. Maybe try giving people a chance. We're all human.
