"Toxic masculinity" automatically assumes, that the problem is with masculinity, or some part of it, which is not true at all. The problem is not with masculinity, the problem is how a given society relates to men and boys. Therefore the term is inapplicable. Some societal expectations are toxic, not some aspects of masculinity.

Men may be more prone to violence, but it's a very very small minority of the population who was actually born with antisocial disorder... Violence is a "tool" that can be used for good or for bad. "Bad" or "good" is not inherent to human beings. Wether someone turns out to be a valuable member of society or a fugitive, it depends on their upbringing and environment.

If boys and young man can not channel their masculine energies correctly, if they are not shown ways to use their violence for good, if they have no real life examples (eg. fathers) as to what does it actually mean to be a Man, they do not learn the importance of honor, the respect of others, how to control their emotions, their rage, their anger, how to behave in position of power, how to be humble, how to trait and deal with women, how, when and where they can show weakness etc. .. They will be vulnerable to corruptive ideas and lifestyle. Bad people are made, not born.

Single parent households are insufficient to "produce" healthy children, every single research shows that these kids will have numerous disadvantages, boys even more then girls.

We can not erase the "bad" side of masculinity nor should we, because certain traits ARE inherent, and by trying we are only going to produce a bunch of disfunctional men, full of confusions. We must tech boys how to be masculine and how to use it for good. We need more masculinity, not less. We must keep fathers around, we must find mentors and role models, we must have more male teachers. But before anything, the gender war must stop, and the use of inappropriate terminologies must cease. So instead of "toxic masculinity", let's talk about the "toxic societal expectations towards men".

In any case, the worst thing we can do is what "we" do today, wielding a crusade against masculinity on the basis that it can potentially turn out to be harmful, and as a solution we try to enforce feminine traits on boys and force them into an environment (school) which clearly doesn't suit their needs. We can't resolve problems with masculinity by effeminating boys.

Further, the notion of "toxic masculinity" does not only harm boys. It harms girls just as much, because it causes (often unconscious) resentment, mistrust and dread towards boys/men and makes it virtually impossible for them to maintain healthy romantic relationships. So if you ever wondered why divorce is on the rise compared to population growth, here's one plausible reason.
