Most of these articles exist not because of the trans people, but because other people are trying to control them or actively make their lives worse.

Like, if the results were "Canadians could not care any less if Bob wears make-up or not" there likely wouldn't be an article, and the 0.33% of people would get closer to 0.33% of our attention.

But, "Canadians are becoming more hostile towards trans people, which might be a result of politicians using them as a wedge issue", that's an article. Especially when one of the authors is a professor of gender studies, which makes complete sense that they wrote about the answers of these questions.

This survey had a number of questions, mostly not about trans issues.
