You want to really know what I hate?
I hate theists that denigrate science and claim to know, without any formal study, more about abiogenesis, astronomy, biology, the Big Bang Theory, cosmology, evolution, paleontology, physics, thermodynamics, and science in general than people that have devoted their entire lives to the study of those fields.
I hate theists that claim to have an open mind while at the same time rejecting any evidence in any field if it contradicts "the scriptural record".
I hate theists that claim to know what atheists think, know, feel, love, hate, believe, want, and have "written on their hearts".
I hate theists that use their interpretation of their religious texts to justify their abuse, bigotry, homophobia, persecution of others, and violence towards those that do not share their beliefs.
