I agree, and also the standards for shittiness today are set quite low. There have been (and still are) truly shitty people, even monsters, but the most common case is simply that of a flawed human being. Which we all are.
Black-and-white thinking is in vogue right now. Obviously extremes exist, and there have been people who were completely irredeemable, but the vast majority of persons, opinions, and even actions lie in the vast sea of grey between those two extremes.
Like, if I went to someone's house, and they seemed to be big fans of Hitler's paintings, it would be a definite red flag. But if there's a painting on the wall by an artist who made a socially insensitive statement in 1972 or something like that, I'm not going to really care.
