To be honest, as organized religion seeks out to destroy the freedom of others, why is everyone such a stickler about freedom of religion? Read some history books. Religion is responsible for a lot of horrors in the past, which still even exist today. An it's not just slaughter I'm talking about. Just take a look at some of the stances GOP candidates take.
No matter what, religious faith tries to dominate everything. Christians are taught to keep their faith and even potentially spread it no matter how little sense it starts to make. It's like a zombie virus, except it focuses less on killing and more on staying alive so religious leaders can still have power over people.
