Twice, since I wrote a piece advocating a pro-gun, pro-business, pro-property rights stance, I've been called a leftist or near enough to count.
From the natural extension of President Bush's "fer us or agin us" to Rush Limbaugh's "we want moderates to vote with us, but they'll never be accepted", there are elements in the Republican Party who believe that if you don't toe every line you simply are not good enough.
Democrats certainly grouse about their Jim Marshalls, but outside of Joe Lieberman being skewered by the netroots, their party is never so quick to roll out the scarlet letters.
I've been called a liberal before and I'm sure I will be again - sometimes with humor, sometimes with venom. There are certainly differing levels of silliness in all politics, but what is far from silly is the belief of Republicans that all political discussions are all or nothing affairs.
As every gambler knows, if your only strategy is all or nothing, eventually you go bust.
