The question in that survey is different: it asks whether people self-censor because of others. That's pretty different than whether inclusivity is a worthwhile goal, and surveys are notoriously variable based on wording. For example, I would answer yes to that question, I censor myself to avoid offending people (I have done so in this thread, to try to keep it constructive), but I strongly support work to make colleges and workplaces more inclusive places.
