I've never come across "leftist" as a synonym for "secular" before; to me, they are orthogonal terms. You can be be leftist and religious, or right-wing and secular.

You're a Brit, zooter.
I'm talking to Americans - you know, those folks you Brits so often call "stupid" and worse.
Now here in America, the Left constantly refers to "neocons," and "right wing religious extremists" and "bible thumpers" and "fundies" and "rednecks" and "fascists" and "Nazis."
Any Leftist knows instantly what you mean by these vile, hateful pejoratives.
You're talking about a Republican - someone who didn't vote for Obama, or Harry Reid, or Nancy Pelosi
Just as there are human beings who are born with neither male nor female organs, while other humans have had their normal organs removed or radically altered, the description of "male" or "female" is not ALWAYS perfect, is it.
But in GENERAL, we can assign humans either a "male" or a "female" characterization. Yes, it's true too, Leftists can make the distinction difficult to assign, and they do this on purpose.
So too, you are generally either a conservative or a liberal.
Middle of the roaders have to take a stand, don't they.
Obama or McCain. Choose only one. Any other selection is utterly wasted.
Why Leftists are so terribly offended by being called "Leftists" when they absolutely delight in calling conservatives "fascists" and "Nazis" and "racists" and "stupid" is just part of the ubiquitous dishonesty, the pervasive hypocrisy of the Left.
