BTW, who are those millions you want to protect? Are you afraid otherwise sensible people will be infected by some opinions expressed on media? Isn't this a bit paternalistic?
It's better to fight the enemy in the open field; let's have people talk and show who they are and what they actually mean by what they say. Let's criticize what is wrong with what they say and not just said by somebody that got lumped together in the same camp. Let's have an open a tolerant society, in which intolerance itself is exposed for what it is openly and not given ammunition by being intolerant of any people.
You're coming at this based on the idea that everyone is rational and sensible and (re)evaluates their views based on logic. Our brains don't work like that; literally all it takes for someone to warm up to an idea is being repeatedly exposed to it [4], and that's before you even get into things like confirmation bias/pleas to emotion/peer pressure/etc.

And yeah, it sucks that people on the margins of that such as sex workers get hurt, which is why we need to push to change those stigmas. But the alternative is letting open pedophiles teach your kids, or asking Jews to defeat their genocide-preaching Nazi coworkers in the “marketplace of ideas”. So all things considered it’s a fair trade.
Of course not. Media and narratives matter. Fascism has succeeded in the past at murdering millions of people. There is no fundamental reason why it couldn't happen again.
Letting people talking about things even if we don't like them, doesn't mean suddenly you have to bend to their narrative and make them control all of the media. But you should return the favour and not fully control the media too.
And I'm saying you should speak to some historians about this claim.
Always interesting that stifling the fascists and Nazis is so popular* but no one ever mentions the ongoing need to silence the communists, who are in the same "ideology with a 7-figure body count" category. Why is that?
