first of all you have to be a non thinking drone with (ironically) a small amygdala to think you would desire a smaller amygdala. This is a very connected part of the brain we are just starting to understand. Its very likely important in forming all sorts of associations ... in essence the bigger amygdala probably means a higher emotional IQ.
next...
because if you were to reduce that portion of the brain in a conservative you would get..
a. more psychopaths (research on pyschopaths showed reduced amygdalas
b. less social or anti social drones
c. people who could not recognize when a lying politician is reason working for the establishment and not the voters. (see below) (the amygdala is probably the center of ones e
In short you would have the perfect drone like big govt loving leftist moron voter who feels good about being a fool.

So what does the amygdala actually do? “[It’s] strongly connected with almost every other structure in brain. In the past, people assumed it was really important for fear. Then they discovered it was actually important for all emotions. And it’s also important for social interaction and face recognition,” Barrett says. “The amygdala’s job in general is to signal to the rest of brain when something that you’re faced with is uncertain. For example, if you don’t know who someone is, and you are trying to identify them, whether it is a friend or a foe, the amygdala is probably playing a role in helping you to perform all of those tasks.”
Barrett says it is commonly assumed that the size of a structure reflects its computational capacity, noting that if your larger amygdala easily allows you to identify people you’ve met before at a cocktail party, you will have a much easier time connecting and socializing. “You can imagine that might be one thing someone with big amygdala might be better at and that might lay the foundation for easier formation of social bonds,” she says.

How unfortunate for conservatives that there are no spot reduction exercises for an enlarged amygdala.
