Furthermore, conservatism is generally not a doctrine proposing new ideas and solutions, only reactionary defenses like:
1. We are US. Better than rest.
2. The world is fucked and nothing can be made better.
3. Shut up because this is just the way things are. .... etc.
Realism, or the conservative worldview, was first codified by Genghis Khan, the Vikings, and other state and non-state actors who believed that they were superior to others. It is co-conspirator and brother to jingoism, racism, classism, and nationalism, all sentiments that contribute heavily to world problems today.
Liberalism was spawned during the Enlightenment.
Which do you think is more conducive to discussion, thought, and idea?
