This is win. It is so much win.
That said, I really prefer the term marriage equality over same sex marriage or gay marriage. Why? Because not everyone who wants the ability to marry identifies as gay (lesbian, queer, bi, or a couple with a trans person who now identifies as straight), and unless you’re checking chromosomes, you don’t really know if people are the same sex.
All of this said, I love love love this picture, and think it makes a brilliant point, both for marriage equality, and hopefully eventual gender/sex equality, that our country has still yet to practice.
Plus, I love me some animal macros in the morning.
