People marrying people they meet on facebook etc (all that generic crap), people marrying inanimate objects (I saw a guy marry a doll), people marrying animals, and some marrying video game characters, get over it.
They chose their soulmater, and besides, according to Darwin, our species is flawed enough as it is, as most of the population should've died off to keep the gene pool clean and free of mutation, but if you let everyone live you get trash-talkers, drug-dealers, pimps, and people who just cannot think straight (although, by our culture, it is deemed inappropriate to laugh at others misfortune, maybe he can't help it).
