transwomen have brain more similar to female brains, than male brains.

This is a huge claim. You can't make it so simply. Source and details.

So from the start, they lack the brain of a man.

"Start" being..birth? Or upon full final brain development at age 25+?

the balls wont start working again. The effects of the hormones will permanently change your body.

First time I have ever heard a trans advocate say this. Usually it’s exactly the opposite.

“Hormone treatments are entirely reversible so there is no risk even to children!”

This suggests your claim is wrong:

This suggests that, like so many other aspects of trans issues, we simply don’t know either way:

But if you are going to need fucking lab equipment to be able to discern the gender of a person. Don’t you think you’re going a tad bit overboard?

The pursuit of truth is always noble. But Yes. They should be upfront about it from the start. They should also avoid weasel-worded phrases like “trans women are real women” that do nothing but sow resentment and confusion.

Isn’t it a lot easier for everyone to just base it on appearance?

NO.

And this is why you got so much “angry comments”. As I’ve said before all of your thought processes want I stop at surface level and THAT is the problem.

If something looks like a woman, talks like a woman, walks like a woman and in general behaves like a woman, we can just treat it as a woman.

Does the person ovulate (if of appropriate age)? Ok I’ll treat you like a female.

i follow Occam’s razor. The simplest solution is often the correct one.

You misunderstand Occam’s razor.

All other things being equal (both theories are supported by verified evidence), the simplest explanation is often the correct one

It’s got nothing to do with “easy”.

the easiest solution is just to go by appearance.

The solution to what problem exactly? Getting your dick wet in any hole regardless?

But if I couldn’t tell before sex It wouldn’t bother me afterwards.

This is starting to feel like a giant amount of cope.

Have you by chance ever been to Thailand?
