See it like feminist top trumps in here.
Just because there are more incidents of male>female does not make female>male any less of an issue, it's still excatly the same. Infact more of an issue support wise I'd say as is it's less likely to be reported as people don't believe it.
A man talks like that he is a potential wife beater, a woman talks like that it's a "joke" as what exactly is she going to do about it.
Abuse is a 2 way street and it's quite disgusting the lengths women will go to, to ok it when it happens to men. It's no good saying, "It's wrong, I don't agree BUT......" It's not acceptable no ifs no buts.
If it's not acceptable for a man to say, "I want to kick her head in and rip her tits off" in jest it's equally not acceptable for a woman to say about a man, "I want to puch his face in and chop his dick off" said in jest or not.
It's all about repsect for another human being IMVHO it's not acceptable to talk about any person like that male or female and any decent person wouldn't. People who talk like that always come across as a bit unhinged to me anyway.
But with regards to the op, yes huge double standards, you only have to read this thread to see that, people trying to find justification as to why it's more "acceptable" for women to say things like that. When it's not, it's just double standards.
