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.

Ex Input:
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: Just as elderly people should not be barred from marrying because they cannot reproduce, so gay people should not be barred from marrying because they cannot reproduce with each other.

Ex Output:
Similar

Ex Input:
Sent1: It's not as if these people will switch to being straight if gay marriage isn't allowed.
Sent2: If gay couples are allowed to marry then any combination of marriage should be allowed as long as it involves consenting adults.

Ex Output:
Not similar

Ex Input:
Sent1: If marriage can be redefined to include other arrangements people may want (right now, same-sex couples are trying to do this) then most certainly it can be redefined to include more people in a relationship to have it apply to.
Sent2: Using the same logic, doesn't giving couples benefits, without marriage, to gay and straight couples, probably hurt polygamists too, and hurt single people who just want to co-habitate, but don't want to register for as a couple?

Ex Output:
Not similar
