Earlier quoted context omitted.
Curtis Yarvin is a software engineer, so if you want to make the analogy honest, a blacklist would be a large contingent of software companies refusing to hire him under any circumstances. Dalton Trumbo wasn't pressured not to speak at conferences because of his political allegiances, he was barred from working period (and eventually jailed!). This has absolutely nothing to do with a blacklist.
So you're saying that this mob is unhappy with him speaking, but has no issue with his being employed? Like this? https://twitter.com/justkelly_ok/status/713222987537756163 "In case you think it's just LambdaConf: Google continues to employ one of Moldbug's most devoted followers." "Tech employees: it's time to hold your execs accountable for lack of action. My tweets aren't gonna do it alone."
There's a lot of hypothetical rabbit holes to go down with this, but ultimately this is a distraction from what's being discussed, which is a person choosing to withdraw their workshop group from a conference because of the opinions of a speaker. Boycotting, protests, or simply declining to not participate are fundamental methods of democratic action. It's laughable to me that anyone would equate what's being talked about here with a suppressive measure.
