If his exposure to anime is the same as mine in the past 10 years (sickos posting their fetishes in cartoon form), I think I'd consider it satanic, too.

What did you even watch the last 10 years? 10 years is such a long span of time, there's been tons of amazing shows out there with thought provoking storylines, good characters, amazing animation and great soundtracks. Just last year and this year(with season 2) we've been graced with Komi can't communicate, an anime I feel is as perfect as they can get to the point where even very critical friends of mine couldn't find one thing to actually critique(just nitpick).

I'd agree with you there's some degenerate stuff out there, I will vehemently disagree with you when it comes to it all being the same, you're just not looking outside of your bubble.
