I will go ahead and be the only person to honestly engage with the terms of your question.

There is a movement that started a long time ago and continues today to “domesticate” boys. Boys are invariably more disobedient in controlled classrooms and group activities and so they need to be “broken in” and taught how to conform to the requirements of modern life and education. Girls tend to fit into this structure more easily as can be attested by the higher educational outcomes among women in countries that allow them to achieve it.

With this in mind there is a lot of resentment against this “breaking in” process. This metastasizes when boys hear all about how “toxic” they are by virtue of how they were born, how much more trouble they are to deal with etc. The emotional response is to resist all attempts to demasculinize them, even in the case of something as inconsequential as bathroom etiquette.

This is an honest representation of the perspective in question. Don’t get all passed off at me for being capable of presenting it.
