I know this forum is not a place that is likely for extreme views to be completely silenced, due to the fact that the thread I mentioned above has not been trashed or closed, but what about other parts of the internet?
I am not going to explicitly state that some people should not be denied a platform, as some should. I am talking about everyday people that don't have much of a platform anyway, and have their own life and background that shaped the person they are, whether or not that is a very likable or politically acceptable person.
I see the paradox of tolerance (https://en.wikipedia.org/wiki/Paradox_of_tolerance) being turned on its head. Those who don't tolerate the intolerant have become so intolerant themselves that they block the ability of those that are tolerant of being able to tolerate or associate with people that have views outside of what is politically acceptable. That, in my view, is intolerable.
Not to say we should embrace extremism, as we should not. Nor should we approve of it. What is important is that we can maintain contact and reach a mutual understanding. I think political polarization may very well be caused by our current inability or unwillingness to listen to other perspectives. The truth is, dehumanizing those with extreme viewpoints only serves to make them bitter, which can have consequences.
People learn from example. Punishment or any strategy that makes someone feel unhappy or socially rejected only makes that person desire to find ways to make the punishment backfire. This is an innate human characteristic, and it provides an important function. Mainly it prevents others from exploiting or unjustly treating oneself, and without it we would live in an excessively coercive society, as nobody would wish to make the tactics of a tyrant backfire.
Thus, we have an innate instinct to find satisfaction in weakening any political structure or order that we perceive as unfair to us. That is why I had such a poor attitude towards school at a young age, even when it was in my best interest not to. It is important to be able to listen to voices of resentment, or they will try to overthrow everything you believe in.
Hope to see some interesting replies to my view of extremism.
