is using the word god overused?

It is, but I think people can't help it, since it's been so deeply ingrained into our language now. We use the word "god" in daily life even if we're not religious, like "Oh my god!". As a kid, I believed stories of god were just like any old fairy tale... and I still do, to be honest. But I am not gonna start arguing with someone who believes in a god.

There's nothing wrong with that. They are just caught up in old traditions that some ancient guy(not god, but some human) decided, that make no sense for us animals to follow like laws. @_@ Even some religious people have realized they don't need to be so strict, and can support LGBT. A lot of the ancient world accepted homosexuality and alternate genders before Christianity became a thing and churches started banning it or giving them death penalty, essentially scaring society into hating homosexuality.

I believe in God, but I'm against the belief that atheist are condemned to hell. Regardless of if you believe in Him or not, the message is that you should be a good person. After all, I'm a Christian now, but only because my parents were Christians as well and I learned to believe. But perhaps, in another part of the world, a better person than me will be born of atheists parents. Does that make him unworthy? No. TLDR, I doesn't matter if you believe or not, you should always thrive to become a good person, regardless of your beliefs.

What Alizia Kiz said is very good. I believe the world would be so much better of a place if more Christians were accepting like that. Perhaps you are Agnostic, which is that you don't believe in a particular god, but you are not atheist, because you believe it's possible something is out there.

I don't know, I think people of any religion abuse their kids... It's sad but it is not something that has to do with religion. I know that some radical cults will abuse their kids much worse than most, though. Like, kids in scientology will be forced to work and pretty much live concentration-camp type lives. I honestly do not know how it's even legal in USA to keep kids in this condition in harmful cults.
