Marriage is marriage, period - to hang onto the definition of marriage as being exclusively between a man and a woman makes no sense,
Yes, but only because it's a good idea to extend the meaning of marriage to cover lifelong monogamous relationships between same-sex partners, as it costs us nothing and makes them happy.
as even before gay marriage had been legalized in some states, gay people have ALREADY GOTTEN MARRIED symbolically
i.e. even they admitted that their marriage was metaphorical.
When you have sex with your boyfriend, do you call it vaginal intercourse? Why not? How is it different just because you're giving it to some guy up the ass?What is the difference between love and devotion between two men, and love and devotion between a woman and man besides gender?
Words have meanings! You think we should change the meaning. Fine! I agree with you! But the anti-gay marriage people are on solid ground when they say that this is a new meaning.
