All racism is bad. Believe me, I've experienced it all my life. But spikes in casual antisemitism specifically have historically preceded troubling institutional changes in the West. Be worried by what is happening right now.
@deonandan I know of one example (around Kristallnacht) and one counterexample ('68 in Poland, which ended up causing lots of emigration to Israel, but no further lasting effects). Do you have more examples (or disagree about 1968)?
