... joking about men being falsely imprisoned on rape charges should also be fine.
If "rape humor" doesn't reflect people's attitudes about women then it must follow that "false rape humor" doesn't reflect people's attitudes about men.
But most of those who say "Feminists have no sense of humor" in response to negative reactions to "rape humor" would lose their funny bone real fast if they heard the same type of violent humor with men suffering at the hands of women.
It's telling that these 2 types of humor aren't seen with anywhere near the same frequency. I can't recall any woman joking about how she would love to falsely accuse some man of rape.
I believe that attitude and the words which spring from that attitude reflects what actions you either approve of or are tolerant of. Those who laugh when someone imagines committing rape are certainly people I would never trust with my safety or the safety of anyone else.
It's also telling that the solution to this problem for many people is to switch from calling it "rape humor" to calling it "crude sex humor." Once you do this then a wimpy apology is sufficient according to many people's standards.
Their standards are too low and their tolerance for sexual violence is too high.
