Are they necessarily obligated to "help the situation"? What is their incentive to do so?

Some commenters may be expressing anger.

My comment was referring to this specifically referenced comment:

It struck me as defiance rather than anger.

One individual in this comment section used the term "gaslighting." That hardly qualifies as "a lot of the guys." Hyperbole used judiciously can be an effective tool in conveying a message.

Women discussing their experiences is of no consequence to me.

But when Feminists express expectations for men's conduct, their thoughts, or the content of their conversations, I reserve the prerogative to ignore or defy those expectations. I sometimes express my defiance in comments or articles to remind other men that they are not obligated to conform to Feminists' expectations. That is not anger, it is defiance or resistance.

Your final line...

"...are you man enough to actually do it?"

...is a provocative challenge. Predictably, it might provoke some to anger. You should not be surprised.

Whether I am "man enough" is determined by the standards that I have set for myself. Your expectations are irrelevant.

In my case, your final line has not provoked anger. It is easy enough to ignore.

If some men are expressing anger, so what? Perhaps their interests conflict with those promoted by Feminists. Anger can serve as a catalyst that would stimulate action on their part, to rise up and defy Feminists and protect their own interests. And why shouldn't they?
