Up until the last two sentences, the Strawman is right on the mark. Besides, there is evidence of same-sex love being accepted and even celebrated: even in the Old Testament. Look at the story of Ruth and Naomi, and just try to tell me "Where you go, there shall I go also; where you lodge, there shall I rest my head; your people shall be my people, and your God my God. Where you die, so shall I fall, and I shall be buried beside you"(paraphrased, too lazy to look it up) means something other than "I love you, and I'll prove it." And that's not all: these two women apparently spend the entire rest of their lives together, and even when when Ruth has Obed, it's Naomi's reaction that makes the book, not Boaz'. Yeah, I know, "thye wert fUCKIN and thats why GOD hates TEH GAYYS", but the idea that the only way two people can have a deep romantic relationship is by constantly bumpin' uglies is a pretty sure sign that the person saying that has no real clue how human relationships work.
(I just have a lot of Ruthomi feels okay)
