A lot of things can be described as not being at fault, but not helping reduce the number sexual assaults in America. Apple pie. The Toyota corporation. Cows. Vegetarians. The colour blue. If LSL really isn't at fault, as you say, then why is it problematic that it isn't helping? Just because it has sexual content? I don't understand. Doesn't your criticism apply to, well...almost everything in life? (But especially almost every PG or higher rates movie and a huge number of television shows? Most of which have vastly higher budgets?)
(There's also, of course, the question of whether this is even a useful avenue of attack. There is some - confusing and contradictory, admittedly - evidence that violent games reduce violent crime, and pornography reduces sexual assaults. We have a lot of experience trying to repress basic human nature, and we have very little evidence that it ever works.)
Edit @rogerbruan: I've certainly been accused of being overly literal before. :) Still...
The original comment said that LSL isn't at fault. You're saying that it is a part of problem. I'm not sure how to square those two ideas. Either LSL fosters sexism, rape culture, and sexual assaults, or it doesn't. If it does, then it's at least partly at fault for these ills, and if it's not, then it's not bad for society, right? Still, I think you're broadly right: The original commenter was trying to blame LSL, and just phrased it oddly.
