He disagrees with you on the reasons why mtf trans people exist, and understanding him and understanding you, idk why this would be “mask off”. He doesn’t like the existence of mtf trans people, he just wants the justification to fight against the transing of kids to be unrelated to things like women’s sports, women’s spaces, etc, when the existence of those things and the general favoritism of women in our society is why mtf trans people exist in the first place, in his opinion.
