People often have very good reasons to pick the labels they do, but those reasons are often fairly nuanced. The only way to respect that nuance is to honor the label. And you don't even have to be Neil deGrasse Tyson to run into relabelling.
Whether that relabeling is done by a Pew poll that labels you as a religious person because you attended a single religious service one year because you were curious about an unknown slice of culture, or by a friend trying to soften your image by labeling you as something they think is less offensive, it's infuriating.
I can't imagine how frustrating this has to be for someone who actually has the burden of having a voice that people are interested in hearing; when someone reduces a careful and intimate response to a fairly personal question to not only a single word, but the wrong word.
It makes me sick.
