Masculinity isn’t in and of itself toxic, but can have toxic aspects — that’s what that term means. So can femininity. But because we live in a patriarchy, the toxic aspects of masculinity have deeper and wider social implications. You’ve just been complaining about the toxic aspects of masculinity — so you tell me what they are, because you’ve talked widely about them in this conversation already.
And you wondered why we aren’t talking about all of the ways that men are damaged by the (toxic) aspects of society and then proceed to spout off in a defensive way that shuts down actual dialogue. So, you are essentially part of the problem with your completely defensive and combative demeanor.
