Yeah, this would be a dumb thing to say even if wasn't bullshit.
I mean, plenty of people don't encounter antisemitism in their daily life. So what? I don't either, for the most part, because I don't associate with antisemites, but I'm not dumb enough to imply that my social bubble represents the wider world. I am capable of reading, so I do have some idea of what goes on outside my bubble, and I am cognizant of the limits of my personal experience. The conversations I personally have at the dinner table do not have broad social implications.
