...if the people behind this production were tagged as "antisemites" or something. But now it's not a trope, because, well, even propaganda for Israel's exclusivity is thrown in to what is supposed to have taken place 140 years ago in the Wild West.
I totally understand why the people of Jewish origin who run the entertainment industry feel the need to overplay that hand and overrepresent or too positively misrepresent their ancestors on such shows. Indeed, at times we can see this propaganda made gracefully. However, in this episode, the dialogues are really dumb and cheesy. Christian kid asks Jewish kid about his unusually small hat, so we are fed with trivia on what a kippa is supposed to represent. Okay... But then, the Jewish kid asks "Who is Jesus?"... Now, come on... They didn't land in LAX yesterday, these people have been on the continent for long enough to have met Christians. It's normal for the Christian kid to not know about Jewish traditions and lore, but not the other way round!
By the way: In hindsight, I guess it'd be okay to call the show "bigoted" or something because they never hosted a muslim character?
