My take on this is that its just the natural evolution of the old "entertainment medium X is harming our youth". Back in the 60's / 70's rock-n-roll or Elvis the Pelvis was scandalous, in the 80's / 90's claims that playing D&D could make you "evil", then through the 90's / 2000's there was that lawyer advocating that violent games could make you violent, now we see claims of over-sexualization makes people feel bad / inferior. Im not saying any of these are true or false, just that there seems to be a trend.
