So apparently there is a bit of controversy about this set of panels from the recent issue of Captain America:
Apparently members of the Tea Party object to being called out on what they are... a group with ill-defined goals and (oftentimes less than) vaguely racist overtones.
Also, apparently everyone forgot that Captain America is generally one of the more liberal comics on the stands (Ultimate Captain America being the exception that proves the rule).
The New York Times has more on the controversy here. Personally, I think this whole thing is pretty stupid.
