(I will preface everything with saying I'm an agnostic so I have no stake at all in this.)
People are completely misunderstanding what Christianity is. Christianity is the thing that happens with Jesus (you know, christianity comes from the whole Christ thing), where we have this thing called the new testament, which basically retcons the old testament.
Stuff from "the bible" is not all equal, basically, because the bible includes both testaments. The old testament stuff (such as the abortion poison) is retconned as far as christians are concerned, it's not valid any more. No actual christian ought to adhere to this stuff. So it isn't inconsistent to ignore "the bible" as long as the part you ignore is in the old testament. Only jewish people care about that part of it any more.
Also, Hell is a later day catholic invention btw, it's not there in the original ancient greek script of the new testament. The original text just describes a state of oblivion where you dwell until you're purified of your sins for however long you need to do so based on how you lived and then also go to heaven. There's no just eternal punishment stuff.
