You will be given a definition of a task first, then some input of the task.
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.

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.
Output:
Not similar
