The problem here is that everyone thinks their ideas aren't radical and that sharing them isn't indoctrination. I once left a religion, peacefully, not loudly or trying to tell anyone else how to live their life. People still in the religion thought I was radical and dangerous to the fabric of society. Charlie invited people to have a debate. Whether he was right or wrong at least to me with my lived experiences feels irrelevant, if that's dangerous to society then society is wrong.
