We would like you to classify each of the following sets of argument pairs (discussing Gay Marriage)  into either SIMILAR or NOT SIMILAR. 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. 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.
Example: Sent1: Many social conservatives argue that benefits are provided to married couples because, in turn, married couples benefit society. 
 Sent2: We give married couples marriage benefits TO STRENGTHEN the marriage, because marriage STRENGTHENS society.
Example solution: Similar
Example explanation: Both arguments argue that married couples can benefit the society.

Problem: Sent1: If gay marriage were made legal, the amendment would have to prohibit incestuous marriage and polygamy at the same time.
 Sent2: As I've said many times already, there are more similarities when it comes to gay marriage, to all other legal marriages.

Solution: Not similar
