A Society That Has Repercussions for One Political Party and Not the Other Is Unsustainable

I saw a video recently of a crazy Leftist telling a friend of Charlie Kirk, Christian Collins, how grateful she is that Charlie Kirk was murdered. It's stunning that people feel comfortable talking this way in public. How long can this last, where one part of society faces no repercussions for its actions and the other side does? This society is unsustainable, and Americans will eventually be pushed to their limits.
