“Both” sides have crazies. Dems are not defined by theirs. We shouldn’t be either. We must remember at the time all the server nonsense came up the RNC was stonewalling and refusing to support POTUS, same over at DOJ, etc. Trump tried to hire other experienced election attorneys and they refused to work. Those firms are of course no doubt working for the GOP on 2022. Context is very important here.
Main stream Democrats believe a lot of implausibly crazy stuff. I think it does define them. For example that socialisms works. That Jan 6 2021 was an attempted insurrection. That a man claiming to be a woman should be allowed to compete against women in weight lifting. That shutting down the oil industry has nothing to do with rising prices of gasoline at the pump. That taxing can lead to prosperity. That Islam is a peaceful religion. That Republicans are largely racist. etc.
The Democrats have main-streamed their crazy because they are a hive-mind. Nobody free to think critically would come to any of those insane conclusions. One can only reach those conclusions through social pressure and such.
Now outside of the Democrat hive mind you have mostly sane people and some people who have a different crazy than the hive mind does.
