A FACET is a low level issue that often reoccurs in many arguments in support of the author's stance or in attacking the other author's position.
PROBLEM: Sent1: Lots of straight people have anal sex and lots of gay people don't, but I don't hear you calling straights "unnatural".

SOLUTION: Not similar

PROBLEM: Sent1: You: You left out that gay marriage is legalized by legislatures.
