I am being entirely sincere and have no problem with queer men, trans people and furies however they are not my preferences and am not bothered with their inclusion in BG3. I just want to know why Silver seems bothered by the idea of a male Tav being able to a threesome with Shadowheart and Karlach, the two most popular female characters, because it seems they have a problem with polyamory, heterosexual men and bisexual women...
The problem is, that you use the term polyarmoury wrong. It is not about a threesome with anyone, it is when a person loves more than one and is in a relationship with more than one person. The others are ok with that, but don't engage necessarily sexually with each other, because they are tolerant, but not necessarily sexually attracted to each other. So what you want, is a simple threesome, not polyarmoury.
