I can't imagine anyone being so blasé if, say, white supremacists were standing outside a Black-owned business. They would, I'm sure, rightly call that out as racist and vile even if it is protected speech.
But because it's a Jewish shop that's being targeted, it gets an apathetic shrug and a "It's free speech, whatcha gonna do?" When those protests do become violent and morph into a 21st century Kristallnacht, I'm sure the usual suspects will rush to assure us that no, it's not anti-Semitism. For reasons.
