I appreciate your position. That was my position until the conservatives started killing people in the streets.
I also agree on the point regarding education. But to be fair, I don't consider a 20 year old a real conservative, simply because they barely understand themselves yet. A young person who is able to experience empathy will eventually find their empathy completely incompatible with conservatism. It is not possible to experience empathy for others and hold conservative views simultaneously. Conservative views fundamentally defy empathy. Education speeds up that realization for young people, which is why it looks like it "turns them" into normal people.
Many conservatives are college educated. The reason they didn't change in college is because they couldn't feel empathy in college, just as they cannot feel empathy after college.
I'm glad you were able to reach someone who identified as conservative. That's not easy at all. I tried to change my conservative friends, family and colleagues for decades. Getting your friend to change is an exceptional accomplishment. If they are able to experience empathy, then I am sure their change will be permanent.
