I don't really see it that way, most of the right wing forumites are gone now. I'm just sick of "Americans are all this way negative comment negative comment". A joke to two, I can handle, as I have been know to throw out a few myself, but there's a difference between "Canadians drink milk from bags" jokes and "American's are fucking idiots."
Unless I am mistaken and my Canadian jokes are truly offensive, then I will stop, as I can't think of a Canadian forumite who actually makes me angry in any way on a regular basis.
The picture is referring to people like Sarah Palin, I'm sure.
