You’re confusing transgenderism with transsexuality. This man can have a vagina and be he/him, it s really his business if he wants to take testosterone and grow a beard whilst having a vajayjay. Meanwhile, a MtF woman can have a dick if she did not go through sex reassignement surgery. In this instance, both are not transsexual. The trans man is female (vagina=female) whilst socially being a man. The woman has a penis (male sex organ). This confuses some people and is why it is still a debate.
The real reason this all makes social practical sense is because a lot of males in society are not very manly and a lot of women are not very feminine. In the past the words to describe these people would be faggot, queer, dyke, or other slurs. Simply because they did not fit what society defined as “a real man” or “a real woman”.
It’s also important to highlight that a lot of transsexual men and women do not believe in transgenderism because it leads to non-binary genders, genders which are unclear or vague (like the "they/them which means the person feels equally masculine and feminine). To these trans men and women, sex reassignment is acceptable but since they do not understand the nuance between gender and sex (or they do not accept it) like a lot of cisgender people who lean right politically, the debate keeps occurring because of willful ignorance whilst this debate has been closed for over 20 years within academia.
