No they're agreeing with early 20th century communist theorists like Marx. The left has always biased toward the idea that social interaction is politics. And "politics" is just the micro social politics playing out on a grander scale. It's just easier to ignore those things when you're in (relative) power, since, as a straight person, you aren't directly affected by the ability of gay people to marry, or whatever.
Limbaugh was just agreeing with the communists. Oops?
Interestingly there are people in this very thread claiming "everything is politics."
