I used to be really into theming. But now, the default Breeze and Adwaita look good enough that I haven't bothered wanting to change them in a couple years.
That and thmes always appeared to be some degree of "broken" that I just don't bother anymore.
I do always change the cursor to the black Adwaita one, even on KDE. It just feels right to me.
When I did still use themes, Numix, Arc Dark, and whatever "flat" themes that I could find were my favorites.
At this point, it's just "the news cycle"; no need to add on anti-trans.
Reading the news in general is just sadness
