He always seemed like a leftist moonbat, even with Amused to Death. I don’t know which one wrote The Wall, but I think its acceptance as an anthem for those wanting freedom in Iron Curtain countries was completely unintentional. Waters did his concert on the Berlin Wall only afterwards as a way of going along, but my take is that The Wall was only against western authoritarianism, and that Pink Floyd only stopped being fellow-travelers long enough to pretend to say “me too” to the cry for freedom from Soviet oppression.
I just spend my time waiting for the worms, personally.
Waters’ dad, was a Communist, who opposed Britain’s involvement in WWII, until the Nazis attacked the Soviet Union.
