What do you think about atheists?

My father was one or at least agnostic he didn't talk much about it so i am not sure which. My mother is a Christian not practicing but holds the core values at heart. What do i think about atheists? Everyone has the right to believe or disbelieve, the only atheists I dislike are those who act like you comit a crime for saying "bless you" to a sneezing person or "what the hell?' Trying to make everything about religion and remind you of their alleged logical and intelectual superiority.
