I am a season of DSC, the new season of Prodigy, and some short treks behind you.
I started with broadcast TNG, and then DS9. Once I had it available on streaming I watched TNG, DS9, VOY, ENT, TOS, TAS and the movies.
Never was part of the fandom community until the last few years. I can’t imagine people being mad about a black Vulcan or female captain! Star Trek always felt to me (as a straight white dude) as a place where everyone was welcome.
