Enron! I am exactly in your situation (22 yrs old, voted for Obama in 2008, and now learning liberty).
I don’t know what the future will hold, but my plan is to do the best I can to learn liberty and then try to explain it to people when appropriate situations arrive.
One thing that makes me OPTIMISTIC is that I think people have an instinctual love for liberty. I think there are many people who would love freedom and free markets but have been bullied into believing that those things are immoral. I believe when people (especially young people) are exposed to the actual justifications for liberty, they will be hooked for life.
I may be wrong but that’s just my two cents.
