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.

Sent1: I have seen only two arguments (and one of them is restated here) for gay marriage to not be a thing: we have to protect the sanctity of marriage or marriage should only be for people who can reproduce.
 Sent2: We should not argue that gays should have the 'right' to marry we should argue that the definition of ' marriage' should be changed.

Sent1: Nothing would prevent straight couples from the exact same marriage whether gay people can marry or not.
 Sent2: Especially since gays are equal in that they have the same rights to marry as straight people do.
Not similar

Sent1: Yet we've shown that we can have opposite-sex marriage without having everything else, haven't we?
 Sent2: But really the only thing we have to know on the issue of same sex marriage is the Supreme Court believes marriage is a right and right now gay couples do not have that right.
