I don't know dude. We've had vibrators and fleshlights for a long time now and things seem better than they ever have been between the sexes (in western culture).
This seems more along the lines of rock n roll being devils music and video games breed violence type outrage.
I prefer to think of the good this can bring people. Companionship for the lonely, for the disabled (a much forgotten demographic in terms of sex). I don't see the harm... Well until the full self awareness and sentience level AI is reached.
Correlation =/= causation
There were a shitload more factors in the improvement of the situation between the sexes. Like, oh, I dunno, the hard-won work done by people in equal rights movements over the past 200 years, perhaps?
Just throwing that out there.
