Cancel culture is a fight by one group to gain moral superiority over others. When you do that, there is no way anyone can defend including the author. Instead of criticizing the argument, they doubt people’s souls, intent, and motivation, their core values - without a second thought. That’s toxic. Our culture and heritage is built upon trust and respect.
For some reason, cancel culture is dominated by Progressives which is profoundly hypocritical: Progressive causes are about acceptance, forgiveness, inclusion and equality.
