Since October I've noticed that these episodes have been slowly picked off Paramount+ in Canada - in my province at least.
Given the current political climate I can at least think of a reason why they would ban the last 3 to theoretically avoid controversy (then again if they're banning specific episodes due to antisemitic themes you would think The Passion of the Jew would be the first to go, but those are still up lol), but I'm sort of puzzled as to why the first 4 have been taken off? I don't remember anything in these episodes that would warrant them being removed over any other episode. There are plenty of worse ones out there, why do you think they removed those?
It all comes down to bigotry. Big Gay Al doesn't tow the party line so he's not allowed to be gay.
