A message of "THEY" are out there threatening "US" tends to sound very conservative in America. Welfare moms, immigrants, mosques, homos getting married; being threatened by an internal "THEM" and being pissed about it resonates with a lot of conservative political messages in the media.
Imagine if they had Al Franken playing a latte-sipping, arugala eating intellectual liberal-type. He drives a hybrid, gets pedicures, hugs Muslims, etc. Now imagine this character gets all riled up about how those damn Superheroes are out there, with their secret agendra, sickos who are trying to threaten OUR WAY OF LIFE and getting all pissed off about it.
The character no longer makes sense.
