There are two logical possibilities about God, both can not be true at the same time:
1) NO God at all.
2) YES, there is a supreme God, creator of universe.
For either case, it is extremely silly for you to hate/scold/attack/ridicule/slander/etc.........(whatever negative words) this God.
Because, if there is no God, you just talked to the air, your object never existed.
If there is God, what harm can you do unto Him ? Nothing! God is OK up there, laughing at your silly acts!
