I actually wonder how "dangerous" the anti-semitic memes and Hitler-memes/jokes could be for teens.
I was playing OW 2 nights ago with a team full of kids before their puberty and they spouted shit like "Hitler did nothing wrong", "Jews love coins! Goyim XDDDD" and stuff like that.
Here in Germany I see some people I knew from my past who slowly became Neo-Nazis. It also started with Jew jokes and stuff like that, slowly changed their clothes (Springerstiefel, Bomberjacke), shaved their head, blame immigrants on why they cant find a job without even having a middle school degree to full on Neo-Nazis spouting about race superiority etc.
