People who troll <insert show here> are stupid.
People who fanboyishly defend the show (regardless of whether they may be right or wrong) are stupid.
The latter only appear when the former starts a thread, or posts in an already-started discussion thread which was not created with the intent to troll <insert show here>.
If the people who wish to defend the show simply ignore the troll posts, whether they start in a new troll thread, or invade a current non-troll thread, there will be less conflict.
Unfortunately, people are retards.
