TASK DEFINITION: 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.
PROBLEM: Sent1: But this is not the same reason why some people have argued against legalizing same-sex marriage, where biological effects on the offspring of the couple are not an issue.
 Sent2: In the same fashion, if denying a few people privacy on this petition would legalize same-sex marriage, then I would support doing that, for legalizing same-sex marriage is far more beneficial to the people.

SOLUTION: Not similar

PROBLEM: Sent1: In other words, since same-sex couples do not "naturally" have children, they do not need the protections of marriage as opposed to opposite sex couples.
 Sent2: You are using a double-standard that is unfair not only to couples, but to their children, who end up losing the protection of having two married parents simply because other people don't like the sex of the two parents.

SOLUTION: Not similar

PROBLEM: Sent1: What they want legalized is something that the government calls marriage and conveys with it the same rights and responsibilities that are conveyed upon what the government calls marriage between people of opposite sexes.
 Sent2: But same-sex marriage doesn't cause disease transfer; gay people will have sex whether they have marriage or not.

SOLUTION:
Not similar
