They are definitivly not anti imperialists, they are assholes supported by the US that hunted communists decades ago. Everyone hates them, the OP was making an joke about how making an action movie glorifing an terrorist attack (aka american movies) would be treated like garbage if said terrorists where not americans. Because movies that glorify terrorism are garbage, they are only accepted on the US because the main characters are american and the victims are from third world countries.
