Err. No.
"You need to adopt a crack baby because you oppose abortion" is patently ridiculous. There's a lot of things that I oppose and I choose not to do them, doesn't mean I have the right to impose my beliefs on others. Your mileage may vary. Asking if anyone had experienced abortion, and it having an effect on whether you'd do it or not, isn't. The question was whether anyone "participated" in an abortion. That sounds to me as if he's referring to a nurse, Dr., etc that helped perform an abortion. In other words, the graphic nature might change your opinion. I could be wrong but thats how I read it.
But, in the name of fairness, we'll continue this:
How many of those supporting have no idea how babies are made? Would it change their opinion if they were forced to learn how? LOL
