I think some safeguards need to be put into place; if you look at the propaganda-machine-work in Nazi Germany, it can do terrible harm. But in the U.S. under Reagen, the fairness doctrine was scrapped, which meant local news outlets of all sorts could be grabbed up by opinionated multi-nationals, and you get people like Rush Linbaugh spreading hatred unchallenged in rural areas - probably the biggest swatch of territory in the country. That's where "these people" get their news, unchallenged. It's far-right-wing money. I also think hate speech might be covered more directly - one of the tshirts at the riot said in abbreviated form - 6 million is not enough. What do you do with that?
Best, Alan (mind you I've been censored on YouTube and elsewhere myself, I think unfairly, so you might make a counter-argument that it's all in the eye/ear of the beholder. It's an aporia.)
