Oh, absolutely (to all of that). Surveys are a difficult art to get right, especially if you actually want to get people's thoughts without imposing a filter of your own biases. I think partly those two questions rankled so much because the surveys in question are actually mostly pretty good examples and the contrast was... notable. (In particular, given that policies are allegedly at least amended on the basis of things that come up in the surveys, the presence of questions on a potentially contentious issue so badly phrased that any answer could be interpreted as supporting any policy rang instinctive warning bells, quite possibly wrongly.)
