You know, you can’t hurt God.
Either: He exists as believers have stated, in which case we have no power to hurt Him. We merely make ourselves look stupid and state an untruth.
Or: Atheists are right, in which case you can’t hurt what doesn’t exist.
Either way, if you believe in a God who is so fragile that he requires you to defend him, this is a problem.
In case you are wondering, blasphemy commandments are for us. You sin if you blasphemy, harming you, not God.
