I honestly heard so many stupidities which sadly I haven't put them all down on paper. But some I still remember.
-Communism/socialism is utopia
-Every scene in a movie with bare chests and butts is fanservicing.
-Covid is no worse than flu.
-This I heard once (or read in newspaper, I can't remember) about Brexit. One gentleman said, to paraphrase:"We won't the war. We won ww1, we won ww2. We don't need those bloody Germans telling us what to do. We won the war.
-Trump advising people to drink bleach.
-When I said that it's bad to lead the country like a businessman, which Trump does. Someone replied:"And that's why he was a good president. He didn't run the country like politicians".
-Okay, this is fairly subjective, but "Morrison's Batman run is the best."

-Bergman's movies are characters all shouting at each other.
