So two different people on two different occasions heard him say something antisemitic, but unless someone else was around to corroborate something that was said 20 years ago, it’s not reasonable enough to assume he ever said anything antisemitic.

Would second former bandmate Dave Gilmour also calling him an antisemite be enough? https://variety.com/2023/music/news/roger-waters-antisemitic-says-polly-samson-david-gilmour-agrees-pink-floyd-ukraine-1235515432/

Would the leaked email where he suggested writing an anti-Jewish slur on an inflatable pig at his concert be enough? https://antisemitism.org/caa-releases-roger-waters-dirty-k-e-mail-and-interviews-with-former-associates-in-new-expose-documentary/

How about the fact that Frankfurt tried to ban his concert for being antisemitic after he appeared on stage elsewhere in Germany with a Nazi-like uniform plus had a pig with a Star of David on it and Waters went to court to get the show put back on? https://www.theguardian.com/music/2023/apr/25/roger-waters-pink-floyd-wins-legal-battle-to-gig-in-frankfurt-amid-antisemitism-row

Does he have to literally start goosestepping and shouting, “Jüden Raus” while doing a guest spot on The Tonight Show or something? I mean what exactly would convince you that maybe, just maybe, Roger Waters doesn’t like Jews?
