> I don’t consider stereotypes funny. America has a really bad history when it comes to shows propagating racial stereotypes. People finding a stereotype funny is not a good reason to air it on national television.
As stated by OP, this is a subjective opinion: The enforcement of a particular viewpoint on the issue of portraying someone from [insert country/background here] is not an easy problem to solve.
Stereotyping will inevitably occur as a result of generalization & snapshots of an intended (X := culture/background/country/activity/etc): They're the result of picking the most commonly-seen & widely-known/believed aspects of X at that point in time & adding their stylizations to it, in an effort to conserve mental energy when it comes to recalling aspects of X. While bad stereotypes will definitely exist, to dismiss it as an outright "bad" is an overly broad stroke of opinion: They will exist because at that point in time, the stereotypes were relatively accurate to them when it came to portraying X.
> Jim Crow was a stereotype which plenty of people found funny 80 years ago, we don’t find it funny anymore(it was never funny), as we see it for the truth.
...There's a paradox in the "it was never funny" statement: If it was never funny to them, it wouldn't have been that popular in the first place - Either it was funny enough then to still be remembered & now be considered a (racist depiction)/(heavily-negative-stereotypical mimicry) in the Western world, or that it wasn't funny & consequently forgotten about right then and there. Various other states can exist in between the 2 aforementioned extremes, but it must've been funny enough to them to still be noted down in the written word.
