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: That way we can keep the sanctity of marriage between a man and a woman, and gays can still have a "union" with other gays.
 Sent2: We can easily create a word for a legal gay union without destroying or changing the meaning of any other existing word...such as "marriage".

SOLUTION: Similar

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: then why does the state allow couples who can't have children to get married or couples in their 70's and 80's to get married but won't let gay people get married?
 Sent2: And some people, who happen to dislike gay people, should not be allowed to use the state to aim discriminatory laws against gay people.

SOLUTION:
Not similar
