Do you really think trans people go through all that just for the fun of it? I honestly think they have mental problems that won't be solved by mutilating themselves. It's not me to make that decision for them and it's their body but I try to keep myself as far away as possible.

And if a women is not a woman and starts HRT and everything, he’s a dude.

What do you mean a woman is not a woman?

Can you tell that just by looking at people?

Most likely not, but by interacting with people, yes.

Can you tell me the sex of each of those people?

Only from faces? Most likely not. First pic looks like a woman, second like a man, 3rd pic that dude might be a woman, 4th the dude is a woman and 5th I have no damn idea

called them slurs

I don't call people slurs mate, I just avoid interaction.
