I am not going to place much weight on an opinion article written by some dude I have never heard of.
I don't know what world you live in, but I cannot recall a single girlfriend, a single female relative, or a single female colleague in my life giving me an expectation that I needed act like a sissy, more feminized, or to tone down my initiative, drive, and competitiveness.
I am not a big fan of buzzwords, aka "virtue signaling", et al. but we all know exactly what is meant by toxic masculinity in real life and in tangible ways. One cannot spend any time on this board, on the internet, or in real life without knowing in a profound way that there is a segment of the male population that act like complete dicks, misogynists, and sexists. Hoy crap man, that is what 50% of the Trumpist movement is all about. (p.s., yes there are women sociopaths, psychos, and jackasses as well, that goes without saying)
Just because I know some dudes act like dicks, does not mean I internalize it and take it personally. A racist white man means exactly what it says. A racist man. I do not internalize it and assume it applies to me.
Trying to not be a dick to women, to gays, to Muslims, to Jews, and to other men is really not that controversial of a topic. In my experience, I cannot say I am aware of any concerted war on Men, wars on Christmas, or Wars on Easter. I just don't see it happening in real life. You know here I mostly see it happening? That's right. On Fox News, and in opinion columns mostly written by dudes.
