The "radical right" enclaves on the internet are literally the only places where you won't be banned for not falling in line.
We need to have this discussion in more than one dimension. Left/right and authoritarian/anarchist are orthogonal metrics.
I find that a desire for safe-spaces and monoculture spans both sides of the aisle and seems to be a broader trend in our culture today. Perhaps this desire always existed and the Internet's ability to cater to the long tail has simply enabled it.
Also calling the_donald "far right" really indicates the bias of discourse online. Which is part of the problem - people are deliberately loose with language and netizens (at least on reddit) truly believe that Nazis have taken over the Republican party...
What do you expect these people to feel when they are being accused openly of white supremacy and Nazism, simply for not going along with leftist politics? That's a unilateral carte blanche to be violent. Punching Nazis is great but it's a serious problem when you are far too loose with labels, as we've been watching. Silence is violence, right?
I assure you that the millions of non-white immigrants who [reluctantly] lean towards Trump are not white supremacists - but all it takes is a single accusation to literally ruin a life. When that is the status quo, it isn't surprising to hear people say that they are voting right like "their life depends on it" because it increasingly seems to.
Regardless of the justification, you cannot deny that BLM are presently the aggressors, openly rallying to explicitly subvert US institutions. Not everyone has to agree with the culmination of the long march through the institutions.
The premise is that the system is white supremacist in nature and must be torn down. From there it is implied that if you do not support tearing down the system, you are a white supremacist. And what do we do to white supremacists?
Except the vast majority of people who are iffy about what's going on aren't supremacists of any sort. The word "racist" is quickly losing effect.
Politics might not be 1 dimensional, but pendulums are.
