I thought about mentioning that but I assumed they'd say something like "Of course I meant after Biden got the nomination." In any case - I made the mistake of continuing to talk to them. Here's their bio...
Anti-fascist. Cultural Marxist Globalist. Liberal.
At first I thought they are the sort of person trying really hard to be clever all the time. But I seriously wonder if they understand what words mean. I now think the "objective priors" stuff was actually the sincere belief of an utter fool.
Serwer is liberal active on social media. I don't know much about him but I think libs respect him. I wonder if they will attack him online or if they are finally realizing Biden is most likely toxic for the dems going into the elections.
