The state wants us to be liberal so we are "open to new ideas" and "willing to respect our accept behavior or opinions different than our own" because the state is already committing atrocities to the human race, animals, and the planet. The state breeds liberals who leave their alleged 'making a difference' to taking actions within the already established system of democracy and hope that by learning the philosophy and supporting policies within the already broken system, maybe we can somehow eventually help people and pat ourselves on the back.
