It is a very depressing fact that we are willing to abandon those that are so close to us in the hope of pleasing a deity that we have never met. I know personally of one occasion where a child has been kicked out of the family home. I have heard friends in the States (TX in particular) aware of this happening.
It isn’t uncommon. Videos on YouTube can be found of angered parents, this one in particular annoys the hell out of me.
There are also multiple Reddit posts from kids asking for advice from the community. I was reading one in which parents had snooped into the child’s inbox on Facebook, reading his conversations with a friend on how they were no longer religious. His bags were packed and on the drive when he came back from school that day, the door unanswered regardless of how long he had knocked.
To feel such anger towards your own child is beyond my comprehension. Even this is pretty tame in comparison to violence and murder seen towards infidels and those leaving religion in some of the more oppressed regions of the world. How can religion claim to be necessary for morality if love and compassion can be switched off like a light overnight?
