Yep.
This a true story:
in 2010, UCS, while doing genetics research, found a mutated dopamine receptor: the DRD4. It basically make a person a leftist. It occurs in about 25-30% of the world's population, starting around age 18-24
My brother, 11 months older, and I were raised *exactly* the same. He's a far left as they come.
It can make a person 'new-thing-seeking, into arts, creative, a good actor, also bi-polar, sociopath, chronic depression, violent, pscyhopath, hypochondriac, agoraphobia."
how do you think Hitler, Mao, Stalin, Pol Pot..were able wake up each day be completely at peace with killing hundreds of millions on the alter of socialism?
Did you know that Hitler won 30% of the popular vote, which directly correlates to the DRD4 mutation rate?
