Christians, why should I not believe the Westboro Baptist Church?

don't believe no-one believe the kings james bible and the lord jesus as words are easy spoken and said but seldom meant or kept as the truth is in the bible and gods word if you use it and apply it and believee and know it is true cause it is as im a pentecostal christian and i relie onthe lord jesus to guide me and teach me and show me the way thats the only truth .....thank you
