Thanks for the reply, I certainly do not mean to imply transition is "betraying your gender" and I apologize if the way I worded things gave that impression.
I was more saying for a cis man, being depressed and wanting to break out of toxic masculinity is not necessarily a sign that he "must actually be trans". And that the idea of expressing himself in less nonconforming ways (which he may feel he can't do because of the restriction of toxic masculinity) would not be a betrayal of his masculinity, despite what toxic masculinity would have him believe.
