It's not even true that half the characters are LGBTQ when looking at Discovery.
On that show, you had a gay couple (Stamets/Culber), and then starting in season 3, a non-binary character (Adira). Gray IMHO doesn't count, because he never was a main character. He appeared in four episodes of Season 3, then six episodes of Season 4, and was basically put on a bus. For the fifth season, we saw him only twice (once briefly in holo-communication). So an important guest, but nothing more than that. Okay, there's Reno too, but she appeared across 18 episodes over the last four seasons - well less than half of all episodes. Many of those appearances were for only a few minutes as well. And Georgiou, though she's been gone since Season 3.
In contrast, Burham, Saru, Tilly, Lorca, Pike, Book, and Rayner are all not shown as queer. And if you're going to include a character like Gray (or Geogiou, who was never part of the main cast), you'd also have to include characters like Vance, Kovich, T'Rina, etc.
