I don't know if that ~1 year on your account represents your total time in Destiny or not, but if you'd been here for the D1 lore and paid any attention to it, you'd understand this isn't forced diversity at all: it's actually quite central to the development of Cayde as a character. Ana falling in love with someone of the same gender is one of the factors that helped shape Cayde's personality and motivated him to make certain choices that leads to him being the character he is now. There is even a mission in D1 where this story gets told, by Cayde himself, as you climb a rickety old pile of crap colony ship to get to the top and destroy an echo of Oryx. I get where you are at, because I am not a fan of someone weaponizing their life choices to get attention and make others feel less comfortable, but that's not what's going on here at all. It's a long-standing part of the game history at this point, and it's not like you can't play the -entire- game without having this pushed in your face...in fact, if you aren't intimately familiar with the lore, you might not even catch a single hint of the relationship in-game. Bottom line, nothing is wrong with this character arc being a thing, at all, and if it bothers you that much, you need to examine your motivations and thought process to determine why that is. Personal growth is a good thing, determine if you need to get some of that.
