Honestly, I think Culber and Stamets might be the best written couple in all of Trek. Not that it’s a particularly high bar since Trek’s always struggled with romance in my opinion. I fail to see anything in their scenes that comes across as pandering or trying to “sledgehammer” some sort of agenda.
That being said, I find it troubling that anyone would have a problem with there being a wide array of sexualities on display.
The best written couple in all of Trek? Are you serious? Culber is barely a character, two seasons later the only thing we know about him is that he likes opera. That's it. His entire reason for being in the show is for the producers to shout about finally having a gay couple in Star Trek. The whole coming back to life thing was lame and spineless, but at least it gives him something to do/someone to be. Hopefully they will expand on him in season 3, finally.
I have no problem with an array of sexualities on the show, just the sledgehammer approach CBS is taking. 5 gay crew members out of a total of 12 in both shows is just silly. Same as 90% of the Enterprise bridge and almost all of the non-main-cast characters being female in Discovery. It's over-compensating so much it just comes across as pandering.
