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?
Big gay als big gay boat ride is not only one of the most inclusive south park episodes in the catalogue but it was released during a time when even most supposedly progressive people were against gay marriage. If they seriously removed that then idk what to even think anymore.
