Good points, although I strongly disagree with your numbers--99% as the author describes? I don't agree with that at all, because you could almost say that's a CONSERVATIVE mindset, i.e. the folks that think if you just left people alone they'd be ok.
The difference is that Libs think all people (except for evil conservatives) are good, whereas conservatives tend to be more realistic - we understand that there are negative aspects to human nature, and try to plan accordingly (both individually and on the public policy level).
Also, the "system" that the Libs think is so great is a socialist, know-it-all, "benevolent" government...hardly a conservative position. It is we conservatives who are unsatisfied with that system - much to their consternation.
I stand by my figures. Most Libs are utter idiots, sheep-like followers of the uber-wise Liberal Obie Wans. It is the latter that we have to worry about, not the masses.
