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: Placing children with gay couples is unnecessary and harmful - if group homes are the only alternative then it is argued such environments are more healthy and indeed normal than farming kids out to gays
 Sent2: If gay people never formed families themselves, and never had children to look after, one could make an argument that gay marriage was an unnecessary concept.
