That's not fair of you to say I am being disingenuous. Please think before jumping to conclusions.
I really don't want to get into nitty gritty debate over people like PJW, but most of what you bring up plays into my point.
What's your threshold for considering an idea to be dangerous? It could be argued that there are ideas that can cause harmful effects on society, but people also have a right to be stupid. I don't see how believing in the illuminati, chemtrails, soy causing feminization, or that 9/11 was an inside Job are dangerous in the same objective sense that promoting racial violence is.
If you have a problem with people believing bogus things, then think about considering issues around education to be a priority, as people who grow up in societies that don't value critical thinking, science, skepticism, etc., are probably prone to believing dumb things. People won't stop talking about chemtrails because platforms consider it dangerous, and restricting speech around "fringe" topics only validates people's beliefs that the authorities are hiding the truth.
I don't know enough about what PJW has said about Muslims. Can you elaborate?
