Ah yes, the classic. You know whats funny ? I see people using the argument "why would God care I masturbate when we live in such massive universe ?" Or something around those lines and yet they will ask why God doesn't wave a magic wand and make all problems go away. I thought God had more important things to do, according to that argument.
I kind of don't get what they want from Him, if suddenly everything got "fixed", we as humans would just fuck it up again. You know it, I know it. And eventually we would believe we can "fix" things better than Him and oh look, shit like communism is back and we are fucking up again.
The only "fix" is removing free will and I'm sure no one actually wants that.
Maybe, in the end, it's our problems to fix.
