It's why it's pretty funny to usually see someone going off on a rant against 'teenage' anarchists, but then declare themselves as a libertarian...
Liberal is a centrist philosophy on the political spectrum. Further left of it you have socialism and even further left of that you have communism.
Personally I disagree with 'liberals' being 'leftist'. Leftist means socialism, and tends to mean anti-capitalism, including wanting to regulate it heavily with forms of socialism or other kinds of economies.
Now take this even further, and you'll see that there is almost no difference between 'liberal' and 'libertarian', as they both focus on individual freedom. So basically you got two political parties: Freedom A and Freedom B, it just seems that liberal seems more focused on creating opportunity and protecting the weak, while the libertarians don't care about those things.
