Comments on how "feminists" and "sluts" (here, both meaning "any woman who does not submit to MRA beliefs") will end up "sad and lonely" are a constant in any kind of MRA discussion.

It's actually kind of sad watching them say this stuff, because it's really clear that it's just them fantasizing about having power over the people who don't bend to their wishes and therefore make them feel powerless - they convince themselves that they hold something those people want (specifically, the attention of them, the supposed Übermenschen) and that they are denying that which they hold - it's a way of feeling like they hold power over these people in some form, since they refuse to give power over their lives away.

From watching #DontDateSJWs, it seems like it's just a rehashing of that. Gators have convinced themselves that SJWs actually, deep down, want their attention, as they also see themselves as maligned Übermenschen. It's eerily similar to MRA behavior - note how often MRAs fantasize about how feminists actually want to be dominated by men.
