I mean, I can't agree that eternal Hell is okay in any sense, but this person doesn't believe Hell is real. I think this is sort of a "okay Hell, whatever, I'm not going to get upset by something that doesn't actually happen".
if a completely moral and just God deems me going to hell for not believing to be right then that’s ok
I actually agree. But only because a completely moral and just God that sends someone to Hell forever can't possibly exist.
