Religion was once again showed down my throat

[Der/die AtheistIn]

To borrow a George Carlin phrase regarding himself and the Pope having the same amount of authority and just not enough people who realize it, indoctrination that leads to someone growing up to be as unbalanced as your dad sounds is a crime, just not enough people realize it. I'm relieved it sounds like he's the last of that generation in your bloodline (unless you have siblings who took the bait) and that you won't be perpetuating that horrible mindset.

I'm a single child, so don't worry.
