Cancel culture isn't a real thing done by the left
It is actually an invention of the right.
Right-wing media helped usher in the age of “cancel culture,” but now pretend it's an invention of the left

Well worth reading but IOW the Republicans or anyone really that complains about cancel culture are hypocrites. It all started as a meme or a line from the film New Jack City that was used mainly for racists like cancel that person usually because they said something racist. Of course the right took a meme that was mostly used on black twitter way too seriously and seen some on the left fell for it railing against "cancel culture".
Boycotts are protected by the first amendment so if someone wants to boycott an artist or entertainer for whatever reason they have the right to do so. Just as you have the right to complain about the boycott itself.
This has nothing to do with Jon Stewart as to why I'm making the post but Stewart was relevant under Bush but under Trump he is becoming more and more like Bill Maher though still not nearly as bad. I prefer the Tuesday thru Thursday Daily Show hosts such as Desi Lydic much more than Jon Stewart these days.
