Is it impolite to ask a trangesder if they r born girl or boy?

I think you’d get lynched

No

You could probably work that out by looking at who they are now. Though someone might say "i was born a guy but i'm a girl now" someone else might say "I've always been a guy".

Sure. You can also ask them if they are mentally ill or suicidal....but I guess we already know the answer to both ...

no cause u know already XD

but it would be embarrassing if u ask a guy or girl who not trans are they trans lol

generally people don't like when you draw attention to their wrongdoings 🤷‍♂️

It might be. I just can't get my head into their mindset.

Yes.

I doubt they will know.
