Shock comedy is a thing.
It can be insensitive, in which case, you don't have to listen to it, and if you're in the same room as someone who does it, you can always ask them to shut up and they should respectfully do so in that case.
If it's in a video, then you can always turn it off. This all wears off, though. In another 20 years, it won't feel as offensive, nor will it be as funny.
By making these jokes, they are excluding you from their target audience, though.
