There's a quote Charlize Thereon said on the set of "A Million Ways to Die in the West" and Seth MacFarlane overheard it and told her to use it in the film.
The quote is: "There is something about connecting over mutual hatred that is just so much deeper than mutual love."
And it's true. I could deal with a girl who didn't really like all my taste in music or films or books as long as she hated capitalism, rightwingers, neoliberal centrists, libertarians, snobs, cops, TERFS, racists, homophobes, and was down to punch some Nazis at any given time.
