What shits me is Christians (and Jews and Muslims, but it's mainly Christians who do this) who just handwave away the problem of evil. Like fine, I can accept that some evils might arise as a result of human decisions and free will. Things like wars and genocides are done by people. It's difficult to swallow even that much with the idea of a god who supposedly knows all, is capable of doing anything, and is "all good", but fine, maybe free will ultimately supplants all that.
But what I absolutely cannot accept is any claim that tries to square the idea of a god with the triple-omnis with the fact that natural disasters happen. That children die of cancer. You try telling the parents of a child slowly dying of a painful incurable disease that someone could fix it if they wanted, and they completely know about it, but that they won't. And then try telling them that person is "all good". See how they react.
I find religious people who believe in the three omnis after having given it any amount of serious consideration to be absolutely disgusting and immoral people.
