That’s an interesting theory. For the sake of argument, how would you then explain someone liberal converting to conservatism. That’s assuming they’re missing the human genome.
“how would you then explain someone liberal converting to conservatism”
The first successful brain transplant.
The brain is a wonderful thing. Consider the missing genetics as damage. Careful training can cause the brain to effectively route around damaged parts and use other parts of the brain for that task.
Consider a liberal going conservative like a stroke victim learning to write.
Easy, they just found the genome in the top right hand drawer in the kitchen.
...how would you then explain someone liberal converting to conservatism...
Ummm.......mugged?
There are several ways to account for it. The primary reason is maturity.
"Any man who is under 30, and is not a Liberal, has not heart; and any man who is over 30, and is not a Conservative, has no brains." - Sir Winston Churchill
Almost all Conservatives have a decided advantage over almost all Liberals because almost all Conservatives were Liberal in their youth before they matured and discovered they were far better at managing their own thoughts than the Democrats.
