Even if it seems to be common sense to those inside the community, there is something to be said about getting actual data on the subject so that those outside the community at least have a touchstone for the reality those on the inside experience, because propagandists are working very hard to muddy the waters on this point and points like this one in particular. It might be a "no shit Sherlock" moment to you, but to people like my Fox News watching extended family, this study is something that contradicts their current mental model of the situation, and something that I am glad I have in my quiver when they start talking about the subject to me.

We’ve been telling it to cis people for years but the refusal to listen to that was palpable.

Here's a Sartre quote about bigotry/fascists that you may find useful:

“Never believe that [they] are completely unaware of the absurdity of their replies. They know that their remarks are frivolous, open to challenge. But they are amusing themselves, for it is their adversary who is obliged to use words responsibly, since he believes in words. [They] have the right to play. They even like to play with discourse for, by giving ridiculous reasons, they discredit the seriousness of their interlocutors. They delight in acting in bad faith, since they seek not to persuade by sound argument but to intimidate and disconcert. If you press them too closely, they will abruptly fall silent, loftily indicating by some phrase that the time for argument is past.”
