There is one thing that you have so far failed to realize. There IS an actual survey out there that I'm referencing here (or that the Colbert Report was presumptively referencing since that's where I saw this on) and that if you have a problem with this then you are bringing it up to the wrong person.
How on earth was I supposed to know you were talking about an actual survey? You provided no reference, nor did you even mention what your statement was based on. And you're still being incredibly vague about the contents of said survey, how it was phrased, conducted, etc. In fact the only detail that you provide is stating that it may have been mentioned on a comedy
show. Surveys are not universal truths.
What you actually stated was of the form: most people feel X, and I stand by my original response to that.
Besides its not polygamy since its all with the same person. I just have to make sure I marry all the clones since the afore mentioned survey would have my hide if I was cheating on my hot sexy wife with one of her clones since adultery is considered to be the worst offense on said survey.
So if I'm dating somebody and I screw her identical twin sister that's not cheating? Score!
