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: 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.
 Sent2: And of course the unspoken result of gay marriage will be the demand that all forms of perversions of traditional marriages must now be allowed because the precedent has been set with same sex marriages.

SOLUTION: Not similar

PROBLEM: Sent1: How does any gay getting married effect any straight couple?
 Sent2: Changing the current state of marriage to allow same sex marriage will not effect straight marriages at all.

SOLUTION: Similar

PROBLEM: Sent1: Now, I am uncertain why gay people should not be allowed to have civil marriage and in fact many people (perhaps most) support civil unions.
 Sent2: Gay people aren't going to accept "separate but equal" civil unions, and heterosexual people aren't going to want to allow gay people to have civil marriages.

SOLUTION:
Not similar
