7. The Un-Americans
A textbook anti-USA statement, The Un-Americans came together in June 2002 - nine months after 9/11.
Originally a trio comprised of Canadian wrestlers Test, Christian, and Lance Storm, they claimed WWE had been discriminating against them and their countrymen for years. They used the Montreal Screwjob as an example and were initially called The Anti-Americans before taking on their better-known monicker in August, and carried an upside-down American flag to the ring in order to draw heat from an audience for whom 9/11 was still an extremely hurtful topic, making this one of Vince McMahon's least tactful ways to generate heat for an act.
Whether it was in good taste or not (hint: it wasn't), the tactic worked. The group was expanded to include William Regal and drew exorbitant heat, primarily through their attempts at setting fire to Old Glory on WWE television, only to be stopped by the likes of Kane, Bradshaw, Booker T, and Goldust.
The Un-Americans disbanded after just three months, with writer Bruce Prichard revealing on a 2018 episode of his Something to Wrestle podcast that the quartet felt uncomfortable drawing that kind of heat. Thus, WWE pulled them apart.
