ripples101, it is good that you accept that you are male, and do not insert yourself into female spaces. Sadly males do sometimes threaten and assault other males if they do not conform to the male sex role. The reason for this of course, is because males want a clear way to distinguish which sex is the dominant sex, and which is the submissive sex. When this becomes disputed, by males assuming the female sex role, other males get angry. As it threatens the illusion men have told themselves; that the hierarchy between males and females is destined.
You are right to combat males aggression towards them, sex role non conforming males need to challenge males instance that performing the female sex role makes them less of a man. Ultimately males need to stop claiming they are "presenting as a woman" or are "trans" etc, and everyone should call them by female pronouns. As that only further entrenches males (and therefore society's) belief that males and females are destined to fulfil dominant/submissive roles.
The main problem is most males are taking the easy way out, by claiming to be a form of "woman". And since males are socialised to believe females should care-take them, as a mother would her child. Many men think it is women's responsibly to solve these real problems males have with other males. Of course females are raised to prioritise males over ourselves, many Mtt's exploit this aspect of females socialisation. They call us "unkind", "bigots" etc, when we prioritise females and refuse to prioritise males, this guilts many women into giving into them. It needs to stop, and males that are doing it need to be called out on it.
