On one level, I get it, it's a funny meme.
But on the other hand, all of the "Kens and Karens" who have been cancelled lately did absolutely nothing wrong. For the 'crime' of sticking up for themselves when they're wronged, they have been cancelled, lost their careers, have significant legal fees, and could lose their freedom.
This situation is far more dangerous than I think many people realize. Talk to someone who lived through Castro's Cuban Revolution, or others. It's the same thing happening here.
It will continue until someone stops it, and right now no one is stopping it. If you try to stop it, the meek cops who kneel to rioters will suddenly put on their jack boots to stomp all over you. Your thin blue line flag won't get you any favors.
You no longer have the right to self defense, or to call the police when you're threatened. And the Karen meme is assisting in this cultural shift.
