[Q]: Sent1: If we want to distinguish between same-sex marriage and opposite-sex marriage, we can simply say, "same-sex marriage" or "opposite-sex marriage".
 Sent2: If we broaden the definition of marriage to include same sex couples, wouldn't heterosexual unmarried couples still be discriminated against?
[A]: Not similar


[Q]: Sent1: So what compelling reason does the government have for allowing gay marriage and NOT allowing incestuous marriages?

[Q]: Sent1: For example, if a state Congress passes a bill that grants additional benefits to marriages and civil unions, a governor could simply line-item veto the benefit to civil unions, which then means that the benefits would apply only to marriage.
 Sent2: Marriage is privilege not a right, because not every heterosexual couple even gets granted the right to marry... the state has a right to regulate what impacts the welfare of the union as whole.
