If we don't stop them, they will crash the country and perhaps the world with us aboard.
As an aside, I once had neighbors who were very permissive parents (they thought they were being "cool"). They let their children run wild. When they went away on weekends, their children had parties at their home and the parents didn't seem to mind...even if they had alcohol and drugs at those parties.
Eventually, one of their children overdosed and the rest of them ended up in rehab.
Point being, there is no natural equilibrium to such permissiveness and the behavior it enables. This kind of behavior is like a wildfire. It won't go out on its own. It rages until it destroys everything in its path.
People always get hurt.
The leaders on the Left WANT the destruction. They believe that after all is destroyed THEY will impose Utopia. What they mean is a feudal state, with a few Elites and the rest slaves.
The poor stupid leftists who follow this are just that: stupid. Prog leaders are the most evil people the world has ever know. Prog followers (all the Dem voters and many Repub voters) are hopelessly stupid.
