Well, you know the whole issue of liberalism as "left" and conservatism as "right" is not entirely accurate. I think that I used to be a liberal, and I haven't changed so much as the political landscape has changed. What used to be liberal philosophies are now considered right wing or centrist. Those who identify themselves as being on the left are what we would have considered to be the ultra left years ago.
I thnik that the political spectrum is more circular than linear. There is still ultra left and ultra right. The ultra left is communism and the ultra right is fascism. That is how people normally believe in political positioning. What I mean by circular is that when you get more left than communism, you get fascism, which is where I see many people who identify themselves as being on the left today. They don't tolerate discussion. They don't tolerate any ideas which are dangerous to their doctrine. But they claim to be for tolerance! They are the ultimate example of 1984; doublethink, newspeak, ingsoc, and the like.
There was a time I was proud to call myself a liberal. I was reacting to what I considered to be rightist fascism. But like I've said, I still pretty much believe in the same things, (with a few exceptions, of course), so why would the left label me as a fascist?
