>The campaign to exterminate any alternative political discourse in the West has been so successful that it's now very hard to even talk about any alternative
I’ve seen no evidence of that and with the severity of your claim should you should include a source or two.
Perhaps you’re confusing people disagreeing with your view with people attempting to silence you. Those are two very different things.
Recall the Occupy Wall Street protest where they camped out in downtown NYC for a month? They broke all sorts of laws but were allowed to stay. That doesn’t sound like “extermination”.
What I do see is violence from communist and anarchists against speech that they deem fascists, but are really just moderate voices. I can provide video links if you need, but it’s common knowledge at this point.
We still live in a democracy and so long as we do, you’re going to have to live with consensus, which doesn’t see things your way.
