Attempts to shame or suppress masculine traits have very negative consequences (just as attempts to suppress female traits have).

Wrong again. Shaming and suppressing violent and aggressive behaviors in our society is exactly what we should be doing. Not making up excuses for it.

We are far better off dealing with that reality than letting politics and our personal moral preferences delude us into thinking that we as a society can be (or God forbid already are) very different from our more primitive ancestors.

I wonder if you hunted down a mammoth today, or died before age 30 like your primitive ancestors. If we're going back to nature, might as well go all the way. Live in caves and hunt for food.

Every great evil the world has seen was preceded by some utopian fantasy.

Nope. Many great evils were preceded by people claiming the world is fine as it is, and can never be changed for the better.
