Most of the comments I've read which are negative are generalisations of trans people. Most aren't based in science or numbers in any way. In fact I've just read a bunch of comments which people are expressing their ignorance and bias of transphobia, or dislike of anything different. 

These decisions don't come lightly by governing bodies. Many of them have spent the last decade researching peer-reviewed articles to base their decisions. We'll also continue for many decades to see some angry person who just doesn't like change, unless it's their approved type of change.
