It depends “Is transphobia a problem” is not the same thing as “Are trans people a problem”.
For one thing trans-women seem to get far more hate than trans-men, which could sway things. Also being less exposed to progressive attitudes could also blind people to what trans people face (which would affect men more).
All this to say that the question asked in the study and what the article makes of it are very different things.
Also the spreads put up as evidence are no where near large enough (2/3 points each way) to push the idea that “cis” men are driving the issue (the study didn’t mention gender identity, the article just assumed).
All in all this article feels more like rage bait than anything that would push the discussion on trans rights Vs women’s rights forward in any reasonable way.
