Linda,
Leftists are inherently lazy - they relish the fantasy that Big Brother (or "Bi Brother" in zzfart's case, but that's a whole nuther story, don'tcha know!) Government is going to lift all responsibility off their shoulders and take care of them from cradle to grave. And as such, they are intellectually lazy, as well ... they don't want to be bothered with thinking for themselves ... they'd rather be willfully ignorant and let one of their commissars do their "thinking" for them.
