The fundamental insanity of religion is summarized in this image:
This insanity is seen in the actions of Christians and Muslims, the thinking of religious politicians, the belief in prayer, etc. The insanity centers on the ability to talk about love when it is convenient or useful, and then to be hateful, racist, bigoted, misogynistic, homophobic, utterly selfish, etc. the rest of the time. No one with any intelligence could read the Bible and believe that “God” has anything to do with “love” – His actions in the Bible are, by and large, abominable. God’s followers tend to act in just the same way. No one could listen to Rick Santorum and not understand the hateful core that permeates his thinking.
It leads one to believe that religion is nothing more than a convenient cover for hate.
