I get that people tend to cluster into two main groups in the US, and that this seems to be strongly encouraged by the existing power structures.
I would also argue that there are a lot of folks (myself included) that see the curtailing of speech - regardless of "side", as a real long-term threat to productive and open communication. We need actual discourse and understanding, or all we're going to get is more us-vs-them polarization and ramping up of rhetoric and violence.
I strongly disagree with most of the opinions being voiced on the (far) right, but if they don't happen in the open they will fester into something grotesque and far more dangerous. Just because I'm disgusted by the opinions of a group of people doesn't it's a good idea for me to make the situation worse by silencing them. Not least of all because we will eventually reap what we've sowed once they grab power again.
I still can't help but shake the feeling that there are those with a real vested interest in a continuing and growing divide (and conquering) of the populace, regardless of the (externalized) cost.
