such bombardment is causal to women feeling bad about being raped

Only partially. Obviously bad shit makes you feel bad, whether or not you have memes about it, but the hypothesis is that bad shit plus being encouraged to feel bad about it makes it worse.

So it seems to follow that you would expect men not to feel bad about being raped, since they don't receive that bombardment.

men don't recieve as much "you should feel bad and let it define your life" but as another user pointed out, it is also not socially acceptable to have been raped, so there is no chance to talk about it and heal.

your whole argument seems to hang together only if I assume that men in fact don't feel bad when they've been raped (which sure isn't my experience, not that I'm any sort of expert) so I was trying to confirm whether you were in fact assuming that.

Well I didn't intend that particular assumption, or at least I don't anymore. A better comparison to investigate would be how people react to being beaten or robbed.
