i think night fox's point is that because there's a majority of straight people that there's really not much to talk about as well as the fact that if you're straight you're pretty much normal in the sense that there's not much quirky things to express about it unlike being LGBT where you have a ton of variation
basically LGBT people have a lot more to express than straight people about their loveuality (in my opinion at least) and that's why a thread is more suited for that quirky minority than the normal straight majority
