I don't deny that the democratic party has and does engage in that type of behavior, I do feel that they are far far better than the republicans.
The democrats (overall, not in its entirety) did vote for raising the minimum wage and curtailing the NSA spying powers. Obamacare is a mess, but it is still a foot in the door for a possible single payer system in the future.
Of course, they were on the losing side on spying and minimum wage. I am also keenly aware that the sole dissenting vote on the Patriot act in the Senate was from a democrat, Russ Feingold.
I also feel the democrats have done a much better job on same sex marriage and separation of church and state. The republicans, if they had their way, would make us look like Russia when it comes to LGBT issues and like a Christian Iran.
But I am also keenly aware that overall the dems are also owned by wall street, and will sell us out on social issues the moment public opinion turns. That said, they still are 100x better than the Republicans and so long as we are shackled by this two party system our only hope of getting ANYTHING accomplished.
I am indeed aware of libertarianism's leftist past. Anywhere else in the world the libertarianism is associated deeply with the left. I like to note to people that the ACLU is also a libertarian organisation and has been around since the 1920s while the LP has only been around since the 1970s to demonstrate this concept.
I desperately want to reclaim the term libertarian for the left.
