Ehh. I think the writer is more than a bit over the top.
True:
It is true that there is a strong perception that if you are a male, it's entirely possible or even probable to lose everything during a divorce. House, savings, kids, etc. I've also known guys to "drop out" of the concept that life's development is "get married". I've noticed a perception to have them described as "men-children", but the ones I know are pretty responsible folks. Java programmer, dentist, etc. They either got badly burned, or saw the financial/emotional downside to marriage. Most date or even have semi-serious long term relationships. I'm in that pool myself. I'm not opposed to getting married, but I do not remotely feel that I need to or should get married.
Not so true:
I have noticed that people believe boys are medicated more than girls. The last paper I read on the subject said ADHD was "underidentified and underdiagnosed because of differences in the expression of the disorder among boys and girls". I'm not really qualified to have a strong opinion on the subject, but I gather the science isn't extremely thorough when it comes to drugging kids out of their gourd.

Not so true: Pick up artists, men's rights activists and the more mundane "Make me a sammich" types are virtuous and enlightened. Plenty of misogynistic folks exist in those ranks, and they're equally as bad as the bad excrement crazy misandrists. Like the misandrists, they get disproportionate attention because they're seek attention.
Bottom line, people often suck and the world would be a better place if folks treated each other with decorum or decency. Like most things in life, I take the libertarian approach: the government should ensure a level playing field, and stay out of the way beyond that.
