But, passing that primary point: I am not at all sure that Rush Limbaugh actually knows what socialism means. I'm also not convinced he knows much about tax policy. And I'm 100% certain he has never actually read Karl Marx, not with the abandon with which he throws around the label "Marxist."
Seriously. If a plan in which folks at the top pay more in taxes than those at the bottom is "socialist," then America's been engaging in socialism far longer than Barack Obama has been alive. It's called progressive taxation. (And, hint, it's not socialism.)
(Sorry, I always know I will get frustrated by listening to such folks, but I cannot resist. The situation is not helped by the fact that news/talk radio stations in Denison are few and far between. My conservative radio station is all there is besides the fading NPR that only seems to come in on a cloudy day, drifting up from Dallas. Air America used to be here, but not only is it gone, but the screaming Randi Rhodes was often just as annoying [if sometimes more informed] than the conservative ranters.)
