Is it possible to be a gay Christian?

I'm interesting in knowing, Roman Catholic member

Although this post was not addressed to me, I'll try to answer.

1. So tell me, why are you a Christian if you don't follow the entire bible?

Christians should follow the Christ, not the book, even if it is the Bible. Not even Christians in the first century followed the Bible in its fullness (actually, that was the question that gathered the apostles in Jerusalem, around 50. A.D. - Apostolic Council).

2. You can't just not consider the bad part and follow the good part only.

This depends on how you understand divine inspiration doctrine. Some Christian denominations teach that God literally used the prophets and apostles as means to pass his message. It is clear that such an understanding leaves us to the conclusion that inspired persons were like robbots or machines. They had no freedom at all and the Bible is nothing else than the holy book without human influence on it.
On the other hand, we can understand divine inspiration in a way in which one artist can be inspired. And that is completely different position. It states that some people have been inspired by God ( theologians would say 'through His grace' - to put it simple: they were permeated by divine energies), but that doesn't mean that, while they were writing, they were completely lacking their freedom. They weren't machines but living people who make mistakes, can sin and who were limited by knowledge and science of their time. That's why you can find some historical or biological mistakes, contradictions, silly and immoral things. Because the Bible is the product of both God and man, the product of synergic relationship between them. It is historical and liturgical (eschatological), divine and humane.

3. Don't come with the argument that 'The OT is not that important' because the NT is useless and meaningless without the OT.

It is important because of its prophetic meaning and value, but Christians are not obliged to follow the Old Testament law.

4. 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?

Sometimes it is clear from the text whether it should be interpreted literally or metaphorically. Of course, knowing the history of ancient Israel, Biblical hermeneutics and similar disciplines can be of great help, and sometimes it is unavoidable and first step.

5. 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?

Actually, they have no the same value. Old testament laws are simply outdated. It means that Christians shouldn't use Leviticus 18:22 or the story of Sodom and Gomorrah against homosexuality (although they do that quite often). Also, some rules are clearly the witness of that time and had nothing to do with God (for example, Paul says it is a shame for male to have long hair)
