It isn't just someone's opinion, it is what is being inflicted upon these poor guys every day. Faced with societies condemnation of the abused man, it is a completely rational response for the abused man to give up and remain silent at all costs. It is a common thing for an abused man. This isn't the men's fault. It is societies fault.
Men are silent because if they speak they are vilified.
If anything, the statistics are underrating the abuse of men. Abused women are accepted today and helped. Men are not so they are silent. That is YOUR pride talking. Abused men don't feel pride - it has been destroyed.
