1: Yes, I can; once again, you can only be born as 1 of 3 genders: Male, Female, and Both with a genetic mutation.
2: Yes I have, and like I said, never has any person been born as a gender other than Male, Female, or both.
3: While it is true the Thesaurus.com does not show gender and sex as a synonym. It should also be note that the definition given to gender is "grammatical rules applying to nouns that connote sex." Which is kind of ironic.
4: What do you mean by a role? The term role as identified by once again thesaurus.com is "duty, or function." While it is true that Males are more physically fit than Females making them more optimal for certain jobs like Military Forces, Heavy Lifting, and other physically challenging jobs. That does not mean that gender itself is a role.
5: For the first 3 or 4 sentences, did you just admit that no matter what people say there can only be 3 genders because nobody can choose, you are just born with it? Okay so let me set you back on track. You just said that you can have a Male body, but a Female mind. That does not change the fact that there are 3 genders. Even if you were born as a man and identify as a Female. Fun fact; you still identify as one of the 3 genders that I am talking about.
Grammar Statement: Capitalizing the words in your comma list is a method used to emphasize the list, and make it more visible. Also, the reason I made fun of your grammar was because you just didn't give a shit about your first reply which honestly is fair on your part lmfao, but from what I have seen in your recent replies your grammar looks fine.
