Apologists make claims about god operating in present day reality. That's testable. And god fails...again and again.

I love referring to their god as she/ or it. Their reaction is very entertaining.

It's annoying hearing them say things like, "Oh, it's just god working in mysterious ways" when something bad happens. It's even more annoying when they credit god for MY achievements. "You're so blessed god gave you this gift" No, I just put in effort and worked hard to do the things I've done, don't credit your make-believe god.

You’re correct!
The next time someone says “God moves in mysterious ways“ or “eye hath not seen nor hear heard nor hath entered into the heart of man… Blah blah blah” ask them to read the next verse. It says, but God has revealed those things to us by his spirit. So no. There is no mystery. Not according to their own Bible!

Some christians I knew were blaming school shootings on, "Well it's because they don't allow god in public schools anymore."

And then a private christian school (Abundant Life) in my state had a shooting.

It seems like their god is fine with the murder of his own followers.

Their god is fine with murdering anyone for the pettiest of reasons.
Do they preach the fundamentalist Christian god in Australia, Argentina, Sweden, Thailand, Peru, Iceland, India, or any one of hundreds of other countries? Nope.
Christians have an insane tendency to see absolutely everything through the lens of their religion. They cannot see things through the lens of culture, the Five Personality Traits, upbringing, family dynamics, drug use, mental illness, … the list is almost endless. Everything and everyone is only black and white but there is a broad spectrum for so many independent factors that contribute to an individual deciding to commit a horrific act … but they’re willfully blind to 99.99% of them.
