Women subjugating men has never been a normal accepted aspect of society Bill. You're missing the point. 

The point is not "all men are bad" or "no women are bad". The point is that men, especially the one referenced in the letter, have more broadly perpetuated a sexist society. But even in Cheryl's letter she talks about men who went against that. 

What you're doing is further diminishing women by removing their rightful voice to complain about men like Richard Jansen. You should be speaking out against behavior like Richard's, not silencing Cheryl.
