Fair points, but the main difference with the state of 'modern' porn is that its accessible to young men during puberty (and earlier), via the internet.
Finding a Playboy magazine in the bushes wont radicalize a 13 year old, but watching BDSM or CNC at an age where you're beginning to form your sexual ideologies can't be healthy.
I completely agree that the intensity of porn that can be accessed at a young age is deeply concerning. I have two sons. If I found a playboy in their room at age 13 we would have a discussion but I wouldn't really care. However, if I walked in on them watching extremely hard core pornography I would be pretty concerned.
