The poll could be broken down a bit better. I believe in a similar one I saw, for example Bisexual Women were the most positive, where Bisexual men were just below Lesbian. Gay men lagging behind, but all were above Heterosexual men and women though.

Likewise I believe how people view trans men, trans women, non binary and other groups also fluctuates. Like there’s people with wildly different opinions on trans men versus trans women, versus people who do not fill a binary position.
