I do. As a rule of thumb, anyone booming the cause of truth, rationality, or common sense is usually trying to smuggle some particular belief in unargued on the back of it. (I've been around LW long enough that that prior is no longer relevant for this particular case. It does have an agenda, but one that is explicitly argued for.)
As well, anyone booing truth, rationality, or common sense, is usually trying to do the same, just by different means.
Voted up because it's intriguing that saying anything in favor of or against truth, rationality, or common sense is a danger sign.
That's plausible, it's just that my mind doesn't work that way. My filter is "is that interesting and plausible?" rather than "what might they be up to?".

And here are two real quotes from 2009:
And in reply:
The quoted text speaks for itself really. So therefore I think LW's admins/web designers should seriously consider replacing the rationality tagline with something more savory.
