Is anyone claiming that these things force people to become completely different than they would have been otherwise? Everything is enabling and exacerbating. The whole problem is the way the norms of our world push people in directions.

The same way young girls are pushed toward eating disorders or cutting or identifying out of being female, young males can be pushed toward fetishes or identifying as sexualized fantasies. Our weird mental culture has set things up so that too many people are ready to fall into unhealthy escapes or enhancements.

Anyway most people are malleable and if they're pushed in those directions constantly and from a young age, it'll have some amount of impact, which will make it more normal over generations, so the push ends up being powerful over time. "things change", for better or worse, and what is seen as a pretty normal sex scene in today's media would have been taboo a few decades ago - but at the same time, some suggestions, jokes, claims or implications that were normal back then are considered taboo now.
