This is a complicated question with no right answer. Both sides of it have been in the wrong historically. I personally believe that the people who have been there longer should have the right to determine what is happening, but there are many reasons for why this view may be wrong, such as the lack of alternative spaces, the necessity of work to survive, the principles of equality, and so on.

However, let us be clear about one thing:

If parent does not harass women and does not send death threats, which seems likely, then regardless of which opinion you hold they are not the problem.

Let's not ever kick people out for civilly holding an opinion, even if we find the opinion repugnant. Civility is important. Civility was violated for the woman behind this post, but not afaik by this commenter.

The real problem are not the people who hold controversial opinions. The real problem are the harassers. Let's team up on them without bystanders having to be scared they'll be next.

Please troll elsewhere. This isn't a request on behalf of the community, it's a personal request as I just ate and don't really feel like throwing up in response to a comment.

Please, I beg you, sort your shit out, or leave.

No matter how trollish or uncivil others behavior may be, please don't be uncivil in return. Encouraging better behavior is one thing. Asking someone to "sort [their] shit out, or leave" is quite another.

"A woman does what women always do"

Do you really think this way? You may want to ask what happened in your life to end up with this attitude. That one sentence basically precludes you from society.
