People ask me why…

People constantly ask me, “why do you (or Atheists/secularists/etc) care so much what other people believe? Why can’t you just let everone believe what makes them happy? What’s the harm?”. Well. This. This is the harm.
Murder in the name of your imaginary friend.
This is the harm.

My God can beat up your God.
This is why I care what you believe and WHY.

If you are willing to believe irrational, superstitious, ignorant, fanciful bullshit, you are much more likely to be capable of using the same faulty reasoning and beliefs to do something in the name of your fanciful beliefs. We all have beliefs. We all think a thing is either true or false.

We, however, do not all use good reasoning tools. We are not all prepared to take the stories of our childhood and the mythologies of our parents and put them to rigorous evaluation. Evaluation of biases and faulty logic. We are not all willing to accept those beliefs as false and face the world head on, no safety net. I care what people believe and why, because people can murder for their beliefs. Do I need any more reason than that?
