Children are getting WAY too much attention they don't need, that's why they fuck up so much, because they are not allowed to explore world but are kept home by anxiety-ridden parents who rather prefer them staring to TVs and tablets watching all that unreal violent stuff.
First ever I seen hardcore porn was when I was probably 6 or 7 when I found such a magazine thrown on the street, at the time I was 10 I had computer and internet and I randomly got to some porn sites either, yet I am still here and never killed, raped nor hurt anyone. I'm not agreeing on kids to see any porn or such a stuff, I even consider frequent porn viewing by adults as bad, but I think if it happens by some accident, the consequences are way overrated, while the bad stuff people expose their children to on daily basis is ignored.
