You described a sibling with a female reproductive system, who has been pregnant. This means that your sibling must be a woman.

That you refer to her as your brother rather than your sister implies that she calls herself a man, and that because she calls herself a man you have chosen to do the same.

You are of course free to immerse yourself in the fiction that she is a man, and make self-contradictory statements like "my brother is a man who has been pregnant." But it would be odd to expect others to agree with this, seeing as it is not based in reality.

It doesn't. As you've been told already, you're wrong about this.

Fortunately for my brother and the countless other trans people in this world, scientific consensus is on their side. You and those in power right now might disagree, but your kind has been defeated before and will be defeated again.

Getting back to the point of the thread, it's fine if you want to hold the personal belief that your sister is your brother. No-one is stopping you from that, nor should they. You could believe she's a cat and gave birth to a litter of kittens if you like. That is your freedom of belief.

However, the CDC should have its focus in reality, not fiction. If a woman says she's a man, she does not somehow transform into a man. This is a nonsensical belief.

It's a bit like Catholics believing that bread and wine actually become the body and blood of Christ. Fine for them to hold that fictional belief if they want to, but it would look ridiculous if the CDC published this within their hematology resources as if it's a fact.

To state that men can be pregnant is incorrect, and has no scientific consensus. The male reproductive system is incapable of pregnancy. You can try to "defeat" this but it's a losing battle, as it is plainly false.
