AHA!

I was trying to figure out how to phrase something like this myself, but thankfully one of flemco's friends came up with a wording that I can stand behind:

Copy this sentence into your journal if you used to be in a heterosexual marriage but you're not anymore because your marriage was whack, yet even after all that, the idea of same-sex marriage being a threat to your whack-ass heterosexual marriage is the biggest bunch of shit you ever heard.
