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: Neither gay nor straight parents have any right to be a parent to someone else's child.
 Sent2: I know many gay couples who have adopted children and are loving parents.

SOLUTION: Not similar

PROBLEM: Sent1: 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.
 Sent2: Even if it was certain that allowing same-sex marriage would allow these forms of marriage, that would only be a downside of legalizing same-sex marriage, it wouldn't be a reason that same-sex marriage itself is wrong.

SOLUTION: Similar

PROBLEM: Sent1: After all the sex that has happened out there, gay sex or straight anal sex (which actually has more participants than gay anal sex), if somebody could "get sick" from it, they would have by now.
 Sent2: Just because a homosexual may marry someone of the opposite sex does not suddenly justify keeping them from marrying a person of the opposite sex.

SOLUTION:
Not similar
