Actually, there's a third--it's obvious. Everything that liberalism has gotten hold of has gotten worse for its influence--education, marriage, child protection, law enforcement, California, poverty, health care, and a whole host of other issues.
Hardly a fact. Conservatives have done just as much good and damage as liberals have. Also, let me remind you that the ideology of liberalism is basically progressivism, whereas conservative ideology is traditionalism. If we listened solely to the conservative mindset on all issues we'd probably not have made nearly as much progress towards equal rights as we have now (obviously more work needs to be done, but we've come a long way). If we listened solely to the liberal mindset, we'd probably be socialist, which isn't a pretty thing, nor does it work. It's a balance of both, and I assure you that the conservatives are hardly correct in all venues.
