How is what he said in any way racist or anti-semitic? He said studies exist that show the discrepancy in immunity, and that it’s unknown if it’s deliberate. That’s the most non-commital you could be without saying nothing at all.

Saying something along the lines of, “Of course the dirty Jews manufactured this virus to kill people off, we all know how corrupt and evil they are!” would be antisemitic. But since people don’t say things like that anymore, the only way to get righteous virtue signaling points and smear your opponents is to set the bar so low that you can’t say anything at all without being racist. Just quoting stats is enough these days.

He’s not a racist. He’s just a guy who frequently has to apologize for or deny saying racist things.
