Yeaaaaah. MRAs aren't exactly known for their even-handed and rational evaluation of anything involving women or women's issues.
In any case, as yummyfajitas points out it's an ad-hominem argument. We should discuss the argument itself rather than the merits of the man making them.
I've even seen a major feminist blogger take her own experiences of abuse, conclude from them that all such abuse is caused by the abuser being male, then tell another woman who'd been abused in the same way by her mother that it was "irrational" for her to be upset by this and that she was "erasing" the blogger's own "lived experiences" by complaining about said blogger's conclusions, and bemoan how she'd been lead astray by the evil MRA community into thinking that her experiences actually mattered.
