And the evidence he gave of this "antisemistism" on Mastodon was simply criticism of zionism (a colonial political ideology) and the slaughter of Palestinian children by the far-right Israeli government, not actual antisemitism (bigotry against ethnic jews). Which is why I pointed out that there are non-zionist jews, why it's racist to conflate all jews with zionists as the OP attempted.
Similarly, if I criticize white nationalists, that's not "anti-white racism".
