Shut-down Argument

A rebuttal used in a debate or argument purely for the intent to overly simplify their opponent's point, even purposefully misinterpreting it.
An example being if A is critical of the president then B can say "you only believe that because your candidate lost the election." The statement can either be true or false, but it's use is to end A's argument. The rebuttal does not actually do anything for the purpose of debate.

"I can't handle talking to fans of the Star Wars sequels. Anytime I say I didn't like it they use the shut-down argument 'you only hate it because what you predicted was wrong.'"
