It seems to me Mr. expert is putting the chicken before the egg here. If we adults didn't provide young people with such glowing, beautiful examples of every kind of perverted, inhuman, corrupt, disrespectful behavior imaginable, they would have nothing to draw on. I'll bet kids in the middle of the Amazon rain forest don't exhibit the same behaviors.
And as far as hate, if it weren't for adults, mostly in the MSM and politicians, mostly democrats, who routinely throw around the race card to keep anger over race alive and well instead of allowing it to heal, bias and hatred drawing top attention in the media, Trump Derangement Syndrome running rampant, ADS (America Derangement Syndrome) everywhere you look, division being favored over unity, demeaning Christianity, once again, where would kids find the anger they display? As usual though, the "experts" only look at the surface and ignore the underlying causes - like treating skin cancer with bandaids - they make a living by selling hatred, selling bandaids to Oncologists..
