It replies directly to your point. You imply that dangerous views shouldn't be kept around.
"Also, it's not a view worth keeping around. There's no evidence to support it and it's just used to justify violence and division."
So I listed some very dangerous economic views that have been proven to fail throughout history, and are widely agreed upon by economists.
So we should silence anybody promoting these views, following your logic. It's for the good of society
We should ban all videos proposing the ex president colluded with Russia too, as it was always a conspiracy theory with no evidence. No matter how much people wanted it to be true. Undermining the legitimacy of a validly elected president should be a silence-able offense. All the better if the party in power or their affiliates are the ones to do the silencing.
Maybe take into consideration which regimes throughout history have used silencing speech the most and whether you want to align with them.
But generally I don't expect holders of these views to acknowledge the hypocrisy of them, or how closely they align to the tactics of authoritarian regimes throughout history.
