> But again, "racist" is a very grave accusation, are you sure that a single inappropriate sentence (missing possibly just a qualifier, "Israeli Jew") at the end of a more articulated argument is enough to qualify someone as a racist?

I didn’t describe someone as racist, I described an argument as racist (the difference is the same as that between a dumb idea and an idea from a dumb person.)

And the argument would be racist even with “Israeli Jew”. It would be possible to rewrite it while retaining some of the ideas in it and not be racist, but it would be a major revision that I don’t think anyone would view as cosmetic.
