There's a difference between acknowledging that a majority exists and letting that majority dictate what definitions and categories we use too much. I imagine she was objecting to the latter.

I think this is especially relevant for an inherently unscientific poll like this where there's no Deep and Important Inquiry going on, so that there's no strong reason not to place a higher priority on making the people taking the poll feel more included even if it's slightly at the expense of accuracy (and I don't think that more inclusiveness does necessarily lead to poorer results. But I'm not too fussed either way)
