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: Regardless of the morality (or immorality) of gay sex and marriage, if people need benefits they need benefits.
Sent2: It's human rights man, people have the right to do what they want, if they want to marry a gay then let them be.

SOLUTION: Not similar

PROBLEM: Sent1: Changing the current state of marriage to allow same sex marriage will not effect straight marriages at all.
Sent2: Possibly, but changing marriage to allow such between couples of the same sex is going against the custom and usage of societies throughout the ages.

SOLUTION: Not similar

PROBLEM: Sent1: The government is not in the business of telling us why we marry someone, whether it is out of love or for some other reason.
Sent2: if we say that same-sex couples should have the right to marry each other, then any two consenting adults should have the legal right to marry each other.

SOLUTION:
Not similar
