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: 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.
 Sent2: Gay people should be allowed to get married if they want to this is the 21st Century there is no reason why they should not be allowed the same rights as everyone else

SOLUTION: Similar

PROBLEM: Sent1: If there are cases where we can not determine what sex a person is, how can we determine if they are homosexual or not?
 Sent2: In fact it is worse, if we ban drugs and find that it was the wrong decision at least it is possible to ban them again, allowing gay marriage is a once only decision .

SOLUTION: Not similar

PROBLEM: Sent1: You did suggest that unmarried heterosexual couples would still be discriminated against, even if we allowed same-sex couples to marry.
 Sent2: We are not longer primitive, so we should allow any couple to marry, as we already allow with straight couples who do not have children.

SOLUTION:
Not similar
