If a joke is an exaggeration, and they usually are, then Trump on South Park ragging on ALL Mexicans is a good joke.If it's based on the lies spewed out by the left, it's not the slightest bit funny. Like when South Park had him running around attacking Mexicans. All Mexicans, not illegal aliens.
If it's based on reality, like when they impersonate him and do that hand gesture and say "Yuuuge" or make fun of the childish nicknames he gave everyone, then it's funny.
Will this puppet show portray Biden's son as a criminal drug addict smoking crack? I doubt it.
Because he never did that.
So it's exaggerated. Therefore a good joke.
It's just you being triggered that makes it not a joke.
