What’s with the Left and their need for “validation?”
They crave recognition for their egos. Virtue signaling is ingrained in their psyche.
They are miserable when they cannot get enough attention.
Toddlers and small immature children do this. They will get attention one way or another, either by showing off or acting up.
This is the result.................
Humans are social. They have need of "acknowledgement" starting with parents. The flip side of it is the crowd mentality (surrogate parent) that doesn't tolerate deviation.
Validation is what one needs when one risks going deviant or isn't sure of their actions.
Leftists, for the most part are taught by repeated conditioning (myelenating nerve axons) for which understanding the central tenets and factual basis is unnecessary by which to obtain positive reinforcement. They KNOW they don't understand said factual bases. Hence the stress when one questions anything (threat of withdrawal of reinforcement).
So think of all that as a positive feedback loop; i.e., it either begs for resources (strokes) until depleted or blows up in anger if withdrawn.
