Censoring the far-right doesn’t make it go away. It just pushes it underground where it becomes even more radical outside of the moderating influence of the mainstream.

I beg to differ. The situation was MUCH better in this regard in Western Europe 15-20 years ago when being openly far-right would get you socially ostracized for the most part, and media didn’t routinely bring far-right mouthpieces on national TV.

That root cause is the total loss of faith institutions coupled with economic insecurity felt by the working class

I do agree with that though, that’s why I’m a commie who wants economic security for everyone (i.e. guaranteed employment and housing) and strong and trustworthy institutions (such as powerful, free and public healthcare and education and pensions, and the end of austerity)
