You know what, after listening to the frot episode again, I have to say I think the comments about the MRA probably being cockrub warriors are kind of a false equivalency. The cockrub stuff is about rejecting an idea of how bi and gay men should have sex with each other, not EWWW GIRLS R GROSS.
Somehow I get the feeling that if MRAs found themselves in another marginalized and mistreated group they wouldn't be such dickholes.
