You just want to rant and even scream. I have better things to do.

Oh please. No one here is ranting and screaming. At any rate, good night. If you ever come up with any support for your fetal brain development idea, be sure to post it.

It's late and I'm not tired, so I decided to look up the material. This is what a pro-trans site says. Note the many uncertain modifiers I highlighted. It's obvious that no one really knows.

There are medical theories about why people are transgender. Some speculate that fluctuations or imbalances in hormones or the use of certain medications during pregnancy may cause intersex or transgender conditions. Other research indicates that there are links between transgender identity and brain structure.

It certainly lends no meaningful support to the hormones and the fetal brain idea.

Excerpt:

"The precise cause of gender transition is unknown. However current research into gender identity and sexual orientation point towards processes before birth as being responsible.

A person's biological sex is determined during the conception process when an ovum is fertilized by one very lucky spermatozoon, and a zygote is produced normally with either an XY sex chromosome pair for a male, or XX pair for a female.

The bodies of all embryos start off as female."

I assume you did read the first sentence here. If you are familiar with reading scientific literature, you know that expressions such as "point towards", or even the "However" at the front of the sentence, indicate that which is theory and far from proven fact.

From another site. Especially note the final sentence. The point in all of this, of course, is that your idea about hormones affecting the fetal brain is just that...an idea. You are welcome to it, but you cannot definitively state that it is the cause. That is my disagreement with you. It MIGHT be a factor. That's as far as you can go.

It was traditionally thought to be a psychiatric condition meaning a mental ailment. Now there is evidence that the disease may not have origins in the brain alone.
Studies suggest that gender dysphoria may have biological causes associated with the development of gender identity before birth.
More research is needed before the causes of gender dysphoria can be fully understood.
