Asked: how not to nit pick the bible?

i was watching the long island medium on tlc, and i was curious as to what the bible says about mediums and psychics and things like such as…
i am a christian but i do not agree with everything the bible has to say, not necessarily what it has to say but more like, dont agree with the continuity of the bible. like i dont think that the original bible, is anywhere near the bibles we have around today. the original books that are now in the bible, were written by pastors, as in pastors who corral sheep around and stuff, the language issue also makes me iffy about the whole bible itself. the english bible had to have been translated over a hundred times, from its original language to hebrew and arabic to 15 century english to the english we have today..
now, my issue is, i personally dont agree with what the bible says about homosexuality. but thats not the issue at hand here, i read that it also condemns mediums. now that i agree with, i dont see the problems with gays but i do see a problem with people who claim to be of God that speak to the dead?

is it wrong that i nit pick the bible? i cant help but feel this way, its just the way i feel about it, the way i believe it? do i stop? should i stop?
