The Westboro church isn't Christian. Just because someone claims they are Christian doesn't mean they are. The Christian faith is about believing in Jesus and treating those around you as you would treat yourself. The Westboro's believe neither as they held their preacher above Christ himself and certainly don't treat others as they would treat themselves.
Almost no one treats every part of the Bible literally. The parts that are to be taken as interpretations are pretty clear on the fact they are interpreted. This strawman atheists poor out about fundamentalists and literal interpretation is old, played out and not substantiated in fact.
The Bible is and always has been referred to as the "Inspired Word of God." Just as a movie is inspired by the book it uses as source material so the Bible is inspired by God but interpreted by man.
As to your other strawman about hate from pro-life, anti-gay etc I can show you ten times the amount of hate from your side just in your post alone. So get over yourself.
