If someone ever heard, were endless discussions of their negative traits without ever hearing discussions of their positive traits as a counterbalance, they would associate themselves and would be associated with only negative traits.

You can see what misandrists are doing by making up terms like 'mansplaining' or
'manspreading'. Just by using terms like 'toxic masculinity', they want to associate men with everything bad and unpleasant while positive terms like firemen have been changed to firefighters to be more gender-neutral.

People also call unhealthy traditional expectations for men "toxic masculinity"
but do not call unhealthy traditional expectations for women "toxic feminity",
they call them 'misogyny' instead... If "women have to be caregivers, to x, y, z,..." is misogyny, then "men have to protect and provide, to x, y, z,..." should be called misandry instead of "toxic masculinity"

The reason people don't use the term 'toxic feminity' when mentioning unhealthy feminine norms is that they don't want to associate feminity with negativity.

And also mainstream media acts as if they cared about men's mental health by using terms like "toxic masculinity". If they worried about male mental health that much they would speak against male issues that men always complain about. Instead, this whole "male suicide is caused by toxic masculinity" rhetoric is less about caring, but is more about mocking and blaming, victim-blaming. It is their way of saying "Oh, he was so depressed and suicidal because he was toxic, he did not seek help, he did not cry enough, he did not open up enough, he did not talk about his feelings enough", not "because he had to deal with misandry restlessly and we need to do something to change that". It is their way of saying "Men's issues are limited to internalized problems, that can simply be fixed by a simple change of toxic male mindset.",

On top of that, people usually blame reckless behaviors in males on "toxic masculinity". Is it "toxic masculinity" or is it simply poor self-worth and self-perception? When considering higher risk-taking behaviors in males, have you ever looked at it from this perspective? Men and boys often exhibit reckless behavior because, growing up, they are told their lives and bodies aren't as important or valuable as female lives. They are not taught to value themselves; instead, they are taught that they are disposable. Society has no problem sending them to war, but not girls. They hear that "women and children" are the first to be saved, implying that they are the last. Additionally, their autonomy is often disregarded, as evidenced by the fact that 30% of male worldwide population got sexually mutilated, mostly as minors. This poor self-perception leads men to see themselves as less valuable and indifferent to the risk of injury.

Thoughts?

TL;DR: Misandrists want to associate masculinity with everything bad and unpleasant... There is a double standard that people call unhealthy feminine norms simply 'misogyny' instead of 'toxic feminity' while calling unhealthy masculine norms 'toxic masculinity' instead of 'misandry'... People use that term in certain way to blame, victim-blame and guilt-trip men.
