I do appreciate the sarcasm, and to your point, here's a bit of gallows humour in return: Allowing someone else to dictate your reaction to words is literal mind control. We cede control of our minds to those other people when we don't have control of our reactions. It's possible (and perhaps the typical case) that most people are habituated to a certain kind of mind control. And hearing or reading something which fits their worldview and moral relativity and subjective value judgments activates a particular reaction in their minds which becomes the expected reaction. It's only when these people hear or read something which is not in harmony with their habituated mind control that they react poorly, shunting the mind control directly into their emotions, bypassing critical thought. And just as though they'd been hit on the nose on the street unexpectedly, their emotional reaction (the thing which I call the "lizard brain") demands the assignment of "blame" so that it can start planning its revenge. Or otherwise respond in a way specified by the habituated mind control.
But to your point as well, it's in our nature though to react poorly to this notion, because it contains some uncomfortable truths about the universe and our place in it. And the lizard brain, having been hit on the nose with an uncomfortable, worldview-challenging assertion, commands to us that surely some fault lies on some level with the person saying the evil words or whatever. But no: It is literally the case that it is entirely within your control how you react to some person coming up to you on the street and screaming "COCKSUCKER!" in your face. I really try not to qualify my statements too much (because not doing so is one easy and practical way to demonstrate how little courtesy we extend to people who say things we disagree with, and how much we force our own value judgments on the words we interpret), but notice I'm not saying that it's not a lot of work to get to that point. And indeed, I still struggle with this mightily every day. We are human, after all. But we are the sole accountable party for our own thoughts.
To further support my assertion, imagine how your emotional, reactionary lizard brain would interpret the Cocksucker Guy if he was clearly a crazy person who lived on the street. Now imagine your interpretation of the same except that it's your significant other's best friend. Or significant other. Maybe you can see where this is going. Now imagine your interpretation of the exact same two scenarios, except instead of "cocksucker" they are screaming "asshole". You've just demonstrated in this simple thought experiment that your reaction is completely and wholly dependent on factors other than the words themselves. And this is my point (and indeed one of the core tenets of Stoicism), that control is an illusion, that real control does not extend beyond the boundary of your own mind, and thusly that the words themselves which you read and hear are not responsible for your reaction, but all this other shit that goes into your interpretation of those words, including your own personal subjective definition and value judgments and worldview.
You do not owe anyone anything when it comes to controlling their minds, and in fact, you are actually doing another person harm when you habituate the mechanics of external mind control by accepting responsibility for the contents of their mind, their reactions according to their subjective value judgments and moral relativity. Supporting the removal of some Youtube channels with unpopular views is precisely how you make habituating mind control more effective than it already is. Society desperately needs more mechanisms for supporting critical thought and (far) less of anything which streamlines shunting mind control around critical thought and into the emotional lizard brain. If anything, our society needs more bad ideas floating around and not less.
So stop helping the advertising industry, the government, mass media manufacturers, racist shitheads, and anybody else who would wish to co-opt the thought processes of those around you! The content of another person's mind is not your responsibility, and arguably none of your business.
