I do. I also grew up on 4chan because I didn’t have an involved parent, and I lived in the suburbs where finding friends to just “go outside and play” wasn’t an option. Consuming that content was genuinely hurtful and probably forever altered my psyche. I have the means and knowledge, in technical skill and life experience, to know how these things work, and protect my kids from that. Most people don’t.
Haven’t you considered that the fact you were exposed to these things made you who you are today am able to say that with conviction. If you had been shielded from the reality on human extremism you would not.
