I've blocked a friend because of the topic that trans men being pregnant

I strongly believe that only females gives birth, so logically if you're a man and decided to be pregnant then you're considering yourself a female I told her It's a scientific fact that only females gives birth she replied to that by saying it's like saying the sun is blue, then the argument ended by her telling me trans men who give birth exist stay mad about it, I was completely shocked of how childish she argued compared to her age But anyways, I personally see trans men who willingly choose to get pregnant are just women I'm really confused I've also saw a lot of trans man on the internet proud of giving birth and their whole content is about being pregnant, how's this possible? I don't think it's common sense at all to be a man and get pregnant What's your opinion? I personally believe that trans men equals men, I have this theory in my head that we have only scientifically three genders men and women and intersex people The men catogery includes trans men and cis men because I strongly believe both are the same and science actually proves the existence of trans people I've many proofs, a simple explanation: you are born with the brain structure in the sexual part being the opposite of your atanomy which causes having dysphoria and in order to treat it you must change your body to match your brain structure, personally I believe you must get on t and have top surgery and a Hysterectomy.. at least.. So if you have gender dysphoria which is the main thing that can make you trans how could you ever allow yourself to get pregnant? You know damn well it's scientifically only for women, if you have decided to be a man you must match the men catogery or you just don't have dysphoria and bored or mentally ill, that's my honest opinion Then she bring up by using my logic, the fact that trans women can't give birth but they're in the female catogery which gives birth.. here's what I believe: Not every female gives birth but No man ever do.. how's that not common sense guys..?
