I would call Obama, and most on the left socialist.
You can call them what you like, but you're not using the word "socialist" in the way that most people use it.
You want to know what a socialist is, find out about Tony Benn or George Galloway or people like that.
I must admit this sickens me a lot. Is there ANY real right wingers in England?
Yes. Plenty. There are one or two of them posting on this very site, in case you hadn't noticed. However, most of them are not as right-wing as the people you call right-wing, because your definitions are skewed way to the right. Put simply, in the UK the sort of people you call right-wing or "conservative" are the lunatic fringe, confined to fringe parties such as UKIP or extreme newspapers such as the Daily Mail.
That said, an awful lot of people do read the Daily Mail.
That said, you'd probably think that the Daily Mail is dangerously liberal.
And policies that you consider insanely liberal, such as government-run health care, are not only standard in the UK but no mainstream politician would ever reject them. No major politician from any of the major parties would consider dismantling the NHS, for example - whenever a politician does say something like this there is an outcry. This is because the NHS more or less works and is very popular, much to the surprise of right-wing Americans who think it's communism.
Why this "sickens" you I can't think. Britain's doing perfectly well without American-style politics, and long may it continue to do so.
Anyway, to point out, the majority of Americans here are leftist too, even though people have reasonably answered the question.
Most of the Americans on this site seem to me to be pretty right-wing, but perhaps they're not by American standards.
Is this word "leftist" a common one in America? It sounds very strange. The term is "left-wing".
