it’s not like we didn’t have LGBTQ+ characters before,
No. We did not. There was no real LGBTQ+ representation on the show prior to DSC. Also the acronym is DSC or DIS, not STD. Not unless you’re going around saying STO for Original, STT for The next generation, ST9 for Deep Space 9, etc.
Saying that the representation was ‘borderline offensive’ is also laughable considering that the show and actors have won numerous awards from people like GLADD specifically for the representation of LGBTQ+ peoples.
