my masculinity be harmful or hurtful

Masculinity is not harmful or hurtful the idea that it is stems from a hateful feminist ideology to which your former friends, and I presumed you, obviously subscribe.

You don't talk negatively about men? You conflate becoming a man with being a bad person

I didn't want to become a bad person just by becoming a man

but you don't talk negatively about men.

The contempt for men I mentioned is evident in the way you regard masculinity. Whether it be the way you belittle all men by declaring our lives to be 'privileged' (I am a man and you don't know ANYTHING about me or my life) or by your belief that being a man means having to actively fight against your innate toxicity, which is what I get from

I didn't want to become a bad person just by becoming a man

btw

I accept that with male privilege I have to deal with these things

I presume 'these things' mean being treated like this? If so you shouldn't.

I haven't done anything? Not really.

No you didn't, but all they did was treat a trans man the way they would treat a cis man.

Please correct me if I misunderstood you; I gathered from your post that you didn't have any problem with the way they talked about men, your had a problem with them subjecting you to that same treatment.
