But I understand that we can't all have the same answer, whatever answer works for you is the one you should use.

But what if I served the moon-god, and he told me to exterminate all athiests like yourself?

What would happen then to your 'you do your thing, I'll do mine' fallacy?

If there is no God, why would it be wrong for me to exterminate you?

After all, I'm just doing my thing, right?

That's why we seperate church and state. If your religion tells you to violate the rights of others then we have to stop you, or you have to figure out which parts of your religion need to be put aside. For instance The Bible is quite clear on what should be done with homosexuals and other sexual deviants, but our laws don't let you do that because we've decided it's wrong to that to anybody unless it's the government doing those things to convicted killers. If you really really want to punish homosexuals the way The Bible says you should you're going to either be a fugitive or you need to go find somewhere that doesn't seperate church from state and will let you do that stuff.

If there is no God, why would it be wrong for me to exterminate you?

Well, there is no universal standard that defines you killing me as "wrong", however that means that there is also no universal standard that defines me preventing you from doing so as "wrong", nor is there a standard that defines a group of people (aka "society") from preventing it under the argument that if we allow you to do it to one person what's to stop anyone else from doing it to anyone else (aka the "Social Contract").

Are you trying to argue that God exists because the consequences of a God not existing are undesirable (argument from the consequences/argument from wishful thinking), or are you just trying to cloud the issue with a red herring?
