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: It's weird indeed that all states except one allow single gay people to adopt children, but many do not allow gay couples to be adoptive parents together.
 Sent2: Not all heterosexual couples have children, and not all gay couples are childless.

SOLUTION: Not similar

PROBLEM: Sent1: I don't care if calling it "marriage" offends people, or violates what they call the sanctity of marriage, gays should have the same RIGHTS that a married couple gets.
 Sent2: But I can assure you that the reason gay people fight to legalize same-sex marriage is not that they want people to recognize them, but simply because they want equal treatment under the law.

SOLUTION: Similar

PROBLEM: Sent1: Only heterosexual acts and unions can actually produce offspring - so gay unions aren't really producing new taxpayers and citizens at all - their relations with the opposite sex are producing new taxpayers and citizens.
 Sent2: Marriage is a public sexual union that creates obligations and sharing of resources between men, women, and the children their sexual union may produce.

SOLUTION:
Not similar
