Ken makes movies. Fine. He has right to have opinions. Fine. But he has no right to abuse of his reputation as a movie maker to promote his personal political opinions. He rather should tell this opinion to his girlfriend. If any. ___________________________________ DEFINITION: Fallacious Appeal to Authority. This sort of reasoning is fallacious when the person in question is not an expert. In such cases the reasoning is flawed because the fact that an unqualified person makes a claim does not provide any justification for the claim. The claim could be true, but the fact that an unqualified person made the claim does not provide any rational reason to accept the claim as true.
