Although this is a perfect illustration of what is wrong with the MRA movement this is nowhere near the worst of MRA's.
Even when they have a point, even when they have a real problem that relates to men they either use it as an excuse to attack women or just show it off in a way that does more damage to their own cause.
And really, there are issues with men that need attention, there are MRA's that are intellegent and do not hate women, but the image of the movement is taken by the loud assholes and misogynists and people who just want a place where they can insult women without being called out for it. And even if there are men's issues it does not mean that women's issues should be ignored either.
Let's examine the "parody" poster:
They seem to be referring to the false rape accusations. Now that is a real problem even if it is rarer than ACTUAL FUCKING RAPE! But don't use a anti-rape campaign poster. There are rapes and trying to discredit an anti-rape campaign is a dick move. Besides, I don't think that anti-rape advocates like false-rape accusations any more than you do.
They could just point out that everyone should be concidered innocent untill proven guilty? You know, just because person X is a suspect of a crime does not mean that they should be ostraciced untill the courts have decided if they are guilty or not. And this works both ways too, your first reaction to someone reporting ANY crime can't be "Well you are probably just lying."
I do admit that false-rape accusations are a troublesome subject. Everytime someone is falsely convicted of rape that persons life is ruined, but if we start beign overly suspicious about rape accusations it means that the real victims won't dare to come out.
(Also, slut shaming and any variation of "he/she was asking for it" should be punishable with a baseball bat to the knee.)
