This seems to be much more of a thing in the USA than else where in the western world.
I just stopped going after while my mother asked me why and I told her I just didn't believe in it any more.
She said she would pray for me and went away sniffling. After that she asked every now and then if I had reconsidered that was it.
My father could not have cared less and my brother had not been to church in years and thought Santa lived on Krypton and was Jesus' brother or some such rubbish.

Stopped going to church for a long time and slowly just started speaking my mind and talking shit about it

My stance on religion is because l have the ability to reason and an above average IQ. Going to church was FUCKING BORING!!! After church l felt like having lunch.
