Steve, that's a bit extrapolate-y. Also, I tend to not see many "right-wingers," (save the one or two extremely vocal who I'll leave nameless), but more liberal people (not necessarily "left-wingers," but left-leaning) on this site. Also, middle-class people tend to be (as a group) rather middle-of-the-road, not so strongly right-winged or left-winged. There seems to be some infrequent banter online about it, but I haven't been able to locate any numbers supporting one side or the other
