Except it does with respect to what the person created the poll was interested in. It is impossible for
any poll to accommodate every possible response to a question. The only way you capture every possible response is to use write-in answers, and write-in answers present an entirely different set of challenges and problems as a type of data. It makes plenty of sense to put non-heterosexuals into a single category from the standpoint of what Jay is interested in.
Don't get me wrong, I get the frustration. Every single time there's a poll about religion, mine is never listed. Now, I could whine about this or I can shut up and accept the fact that I'm a religious minority in a nation overwhelmingly dominated by Christians and the unaffiliated. I shouldn't expect to be treated as anything aside from "other" as a response option. It's unrealistic to expect poll designers to list every single option and it quite simply can't be done anyway. Depending on what they're using the data for, the specifics of my "other" is irrelevant anyway. It's when it's not that I will get fussy, because that's sloppy research. Sloppy research bugs me.
