Men decided they were women's "protectors". Maybe some women still buy into that idea but frankly I find it insulting and silly.
But that is the attitude perpetuated with "there's an aggressive black man" , "I'm feeling threatened by a black man" , "there's an angry black man trying to run me over, I'm fearing for my life", "I'm calling the police", "I'm calling Immigration ", "I'm calling your employer because you're harassing/threatening me".
That's a power that women in the US (at least) have. Having it wouldn't necessarily be an issue, and it could be blamed on men only . The issue is that they know they have it and they use it,frequently and deliberately.
