Unfortunately, irrational behavior applies to both sides but on different issues. I saw it first hand in terms of COVID and my liberal friends. They took the most negative possible outlook and then called you an unscientific idiot if you didn't think it was the only possible outcome. COVID has a 5% mortality rate (even when reasonable data indicated 0.5%). A vaccine is impossible (even when multiple companies said they had promising candidates). Immunity doesn't exist (even when everything except a few reports said it did). And so on.
