Your ignorance is on full display here. The hypothalamus is primarily responsible for regulating internal functions, such as the pituitary gland. It has some function relating to emotions, but primarily in their expression, not their formation. And brain studies have not found differences in the hypothalamus activity between political orientation. The formation and derivation of fear, anger, love, etc. are functions of the prefrontal cortex and the amygdala, as shown by many brain studies. But you can make stuff up if you want.

You are right that religion was the impetus for organizing large societies - many thousands of years ago. Religion is very useful for controlling people and for allowing a few self-chosen elites to seize power in societies. In today's world, however, we have countries and states and governments and all kinds of non-religious communities. And you can make whatever arguments you can imagine based on primitive societies, but there is no basis in what you say for modern societies. What religion does do, as evidenced by your writing, is allow people to just make up all kinds of unsupported claims, because they believe them.
