Have you ever thought where does this hate to woman comes from? There's cleary enough evidence that there are men from all around the world that have this issue therefore it cannot be just label as a casualty of individual cases. You could argue that this kind of people have always existed (call them incels, betas or whatever term you like) and that we're just seeing a rise due to globalization and the internet, however this could only be a correlation and thus not necessarily the causation.
The only people willing to do research about the subject are these same males making any kind of information gathered about it on the very least biased.
It's an interesting phenomema that sadly its shadowed by this whole incel meme.
