German comic which teaches kids how to fight Neo-Nazis, the non-violent way. Such as the following:

In the first edition, Andi and his friends challenge arch-villain Eisenheinrich and his gang, who dress in neo-Nazi clothing, hate foreigners and distribute far-right music at school, to a game of basketball, which invariably the skinheads lose.

This does beg the question, what would Andi do if the skinheads had won the game? Shave his hair and don a brown shirt?

Good old British comics of course, like Battle & Warlord, taught British youths much the same thing. Except it was just Nazi’s that were being fought, and said comics did not exactly eschew violence.
