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: It's weird indeed that all states except one allow single gay people to adopt children, but many do not allow gay couples to be adoptive parents together.
 Sent2: Not all heterosexual couples have children, and not all gay couples are childless.
Not similar

Sent1: If you listen to people talking about the benefits of marriage upon society (Note, DIFFERENT from the benefits the government gives married couples)...
 Sent2: It would require that the government not provide any benefits to any married couples (same sex or not)and their families.
Not similar

Sent1: If civil unions do not provide the same benefits and protections as marriage, then civil unions are clearly not equal to marriage, and again, gay people are being treated as less-than-equal citizens.
 Sent2: If the state wants to offer legal protections and benefits to straight married couples, it cannot constitutionally refuse equal protections to gay ones.
