As a nitpick, you are making the same fallacy of false dichotomy as the test. The claim of 25% of Liberals owning a gun doesn't specify what kind of gun they have.
I suspect only a very few Liberals want Dick Cheney face shooting guns controlled; its the street sweeping police armor peircing variety that gets them excited.
Ooohhh, gets me aroused, too, oohhh, baby...
I think the vast majority of people want some gun control, myself included (though you'd hardly guess that from the most recent "Guns" thread). I don't want ex-felons owning guns, and I don't want minors owning guns, and I don't want crazy people owning guns. I agree that there are certain kinds of guns that no civilian could have a sane use for, though I think writing legislation that would effectively define those kinds of guns is probably akin to digging holes in a lake.
The thing is, remember, I got myself designated as a liberal by answering what I thought the liberalist of the liberals would answer; in other words, I tried to make myself almost pink. And thus put myself in the same category as the biggest, most liberal single group of Democrats - a significant minority of whom own guns.
Do I think they're hypocrites? No; as you point out, they probably just want laws against "assault rifles" and such (which, again, is probably like trying to dig holes in a lake), not confiscation. But was I surprised that this group - the tree-hugging bleeding-hearts that I (temporarily) identified with - had significant gun ownership? You bet.
To me that would be kind of like saying 95% of Liberals have a Bible in thier house, so they must prove that a vast majority of Liberals are actually against gay marriage!
Lots of people have Bibles in their houses through no fault or desire of their own. Mrs. BPSCG and I have three. I bought one because I realized many years ago that even if you think the whole thing "has noble poetry in it; and some clever fables; and some blood-drenched history; and some good morals; and a wealth of obscenity; and upwards of a thousand lies" (Mark Twain), it's a major work of western culture and no person can claim to truly be educated if he's unfamiliar with it. I bought the second because my father recommended it as the translation that most closely hewed to the original language, and it was, in his not inconsiderable opinion, the one that a devotee of Spinoza could approve of. And the third was a wedding gift from Mrs. BPSCG's mother, with sidebars on how to make a good marriage by following its teachings (we have yet to refer to it in the middle of our occasional screaming matches).
People have Bibles because it belonged to great-grandma Martha and she laboriously wrote into it all the births, weddings, and deaths throughout her long life before handing it off to grandma Eleanor, who carried on the tradition. That's how Mrs. BPSCG and I will likely come into a fourth Bible someday...
