question:
Sent1: I think we who support same-sex marriage are very clear that we are fighting for freedom and equality of same-sex marriage, for all the non-heterosexual couples.
 Sent2: In the case of same-sex marriage, I can think of no reason why we should not extend the same rights that opposite-sex couples have to same-sex couples (and plenty of reasons why we should).
answer:
Similar


question:
Sent1: So what compelling reason does the government have for allowing gay marriage and NOT allowing incestuous marriages?
 Sent2: The constitution allows the government to define marriage between a man and a woman, but the reason for defining it that way can't be because they want to use the Christian definition.
answer:
Not similar


question:
Sent1: You are using a double-standard that is unfair not only to couples, but to their children, who end up losing the protection of having two married parents simply because other people don't like the sex of the two parents.
 Sent2: Since same-sex couples are raising children, the children in these families deserve the right to have two parents who are legally married to each other.
