I have a theory regarding the emotional stability and maturity of the left.
We are seeing a great deal of the kind of tantrums that five-year-olds exhibit when they don't get their way. Right up to resorting to physical violence when they realize their arguments are not winning any support among the independents and moderates.
You can see it in the spittle-flinging rantings of the unhinged left on YouTube reels, TikTok, and even in the untrained feeds of people on Facebook. Just look at the trans people and how they simply lose their shit at the least disagreement.
It is reminiscent of a toddler who wants the world to match their view of how it should be, and they are willing to kill to get it.
I need to do more research on the 'ego-centric' development of 2 - 5 year olds.
