Wow... just....
wow. That's disgusting.
Your internal morals and humanity are the arbitrator that decides that the former is nice and the latter is not nice. If you need an external deity in order to make moral judgements, then you're amoral and inhuman.
That's my point. You have no reason to believe that your internal morals and humanity are correct. After all, your thoughts are just a series of chemical reactions in your brain.
Take, hypothetically, Bob the kitten slayer - he genuinely believes that running over kittens is moral cause it's the right thing to do.
By saying that your morality is superior to Bob's, all you're really saying is that your brain has better chemical reactions than his. (btw, define "better" in this context)
And anyway, who says it is wrong to be immoral?
I could just as well take your last sentence as a compliment
