I’ve had situations like this before. What I usually respond with is; “true, there are some obnoxious, selfish, nasty people among us.
But can you honestly say, you’ve never encountered a polite, considerate, resepectful Jew? And would’nt you say, the nice ones far outnumber the nasty ones?
They rarely answer, but then again, I don’t expect one. I don’t need to convince them. I need to convince myself.
Can we stand some improvement? Sure.
Are we head and shoulders above the bulk of society? Absolutely!
