Mystery:Why Do Non-Conservatives Exist?

Conservative principles are based on reason. So why do non-conservatives still exist? Here are some reasons:

1. They made up their mind before hearing conservative principles, and will not reconsider their views.
2. They have something criticized by conservatives in their personal background, and feel compelled to defend it rather than let it go.
3. They pride themselves on doing well in school or reading the newspaper, can't accept that what they were taught was incorrect or biased.
4. They have liberal friends, and want their approval or acceptance.
5. Their job and salary, such as working for public schools, depends on keeping conservatives out of power.
6. They knew a conservative whom they dislike for some random reason.
7. They have trouble understanding some of the slightly abstract concepts in conservatism, such as "more guns, less crime," and "less taxes, more revenue."
8. They are more comfortable discussing simple issues like race and poverty than complex issues like globalism.
9. Media bias acts to caricature conservatism, making it seem unpalatable, conditioning people to reject its teachings.
10. Schools reward politically correct, liberal answers on tests.
11. Unthinking rebellion against conservative parents.
12. Impressionable individuals buying into Bush derangement syndrome, and reacting with emotion rather than reason.
13. A desire for large government inculcated by personal weakness and reluctance to take personal responsibility.
14. A disproportionate focus on biblical passages that appear to support liberal positions, eg the adulteress story, the disciples holding everything in common, etc.
15. An admiration for historical figures whom liberals claim were liberals.
16. Self-destructive or contrarian behavior; some choose to do what is irrational.
17. Charismatic leaders trading on image, rather than experience, can dupe the unsuspecting.
18. Intellectual myopia - failure to heed the long-term consequences of ideological positions that seem beneficial in the short term.
