No. But it's really on both sides. All it takes is one ill-considered statement to bring someone down. If you want an example of it on the right, look at what happens to people who supported the fact that the recent election was accurate. Contradict the Leader once and you're dead.
That of course is not true. However, I have indeed noticed lately that the Left has begun to try to say that Trump supporters and Republicans, etc. engage in cancel culture, too. It appears to be an attempt to confuse the issue and minimize this terrible turn towards silencing and actually ruining people who dare to voice an opinion not in agreement with Left-wing politics.
"Cancel culture" neutralizes, through the use of threats and intimidation, the rights to free speech that all of us deserve and have basically enjoyed. We enjoyed it, that is, until we reached the most recent four years during which the people who lost the 2016 election vowed to destroy the new administration by any means possible. And then it was extended to anyone even suspected of having voted for Donald Trump.
Therefore, until the era of Maxine Waters, Antifa, BLM, and etc., we didn't experience such a concerted effort, with the support of elected officials and celebrities...and for certain we didn't experience it with the perpetrators knowing they can get away with it!
Urging supporters to get in the faces of ordinary people who dare to voice another opinion, "doxxing" (meaning to circulate the addresses of targeted people so that mobs can surround their houses and threaten their wives and children, contacting employers with lies in order to get the targeted people fired, or do something to damage or destroy whole businesses, websites, and etc.), accosting people in restaurants while they're having dinner with their families, and more such practices have become a feature of our times.
This is Cancel Culture. And it means what the term says--to CANCEL the person in every way possible short of murder.
The threat it poses to our society and also where it came from must not be misunderstood.
