suicide bomber

Do you know what i hate most...people who believes in a thing,devote their life for the cause of their belief, try to persuade others to believe in the same thing that he believes in but then never truly understand the basics of their beliefs,never try to put out example of his beliefs and whats worse, have the most irritating attitude that makes other people doubt about his beliefs...
these people always complicate simple things, try to make themselves look complicated,mature and full of knowledge but in truth they are full of crap...
