Things we consider "toxic masculinity" are (for example)
* Sexism and misogyny - that is women are less than or inferior to men, and should be focused on serving them.
* Violence is a reasonable response to being upset
* Men who aren't sufficiently "masculine" (often defined in terms of the above), are also lesser
* Women who aren't sufficiently "feminine" need to be put in their place (understand who's in charge, and who they should serve)
Are there a few idiots who go beyond that? yes. Just like there are idiots who go bizarrely far on any other topic.
But attacking toxic masculinity is not attacking masculinity. It's not attacking men and boys.
If you feel attacks on toxic masculinity are attacks on you fathers/husbands/sons maybe there should be some thought about what about their behavior overlaps the above, and whether you think that's ok?
