Is it possible to be a gay Christian?

[Dystopia]

So tell me, why are you a Christian if you don't follow the entire bible? You can't just not consider the bad part and follow the good part only. Don't come with the argument that 'The OT is not that important' because the NT is useless and meaningless without the OT. I've always wondered, how do theists who follow a holy book know what parts are up to interpretation and what parts are supposed to be interpreted literally? Why do some theists only follow some holy rules but dismiss other rules that are also in the same book and possess as much value? And why do some theists try to interpret phrases or verses that simply cannot be interpreted differently than the literal meaning? Putting it simply, if verse X says 'You shall kill all people of this category', how can we say that 'kill' doesn't actually mean 'kill' but other thing?
