A pair of arguments is considered SIMILAR if the arguments are about the same FACET (making the same argument), and is considered NOT SIMILAR if they do not have the same FACET.

Question: Sent1: Now outside of this country things are very different I know, but I still don't think gay marriage is going to significantly impact this.
Sent2: As I've said many times already, there are more similarities when it comes to gay marriage, to all other legal marriages.

Answer: Not similar

Question: Sent1: So what compelling reason does the government have for allowing gay marriage and NOT allowing incestuous marriages?
Sent2: Furthermore, polygamous marriage has a specific set of reasons why it should not be allowed, and those reasons do not apply to same-sex marriage.

Answer: Not similar

Sent2: Man-woman marriage is legal and gets state goodies, but man-man and woman-woman marriages are illegal.

Answer:
Not similar
