I am honestly confused here. What does that have to do with my point?

Let me go back a step. "Some people would be willing to accept the concept of same-sex civil unions but not same-sex marriage." Do you disagree with that statement? It seems kinda obvious to me, but if you disagree, I am willing to hear why.

If you accept the statement as phrased, the next question is, How can you have a valid survey if you deliberately leave out a large swath of people?

Or is your point to invalidate the opinions of people who frame the issue differently than you do by somehow pretending that they don't exist . . .?
