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: Some folks argue that the laws barring same-sex marriage are not discriminatory because gay people can get married to people of the opposite sex.
 Sent2: But gay people can do that too; if people are going to marry not for love but for benefits, gays can do that by marrying someone of the opposite sex just for the benefits.

SOLUTION: Similar

PROBLEM: Sent1: How does any gay getting married effect any straight couple?
 Sent2: Some suggest gay marriage will merely undermine one of our most fundamental societal institutions, causing countless straight couples to get divorced because exclusion of gays was the only thing holding their marriage together.

SOLUTION: Similar

PROBLEM: Sent1: I have no problem with homosexuality, but marriage should be between a man and woman.
 Sent2: I have no problem with gay marriage, I do have a problem with the invasion of people's rights to believe that gay union is wrong.

SOLUTION:
Not similar
