Now I still believe debating theists is worth it, even though it
If you believe in a god, but not Santa or that aliens abduct humans you are dumb.
Its really not that remarkable thing to say. In fact you believe in your god for reasons that you purport to be true. Now, I can take these arguments and insert Santa or alien abductions and these also become true. If this is not the case, then the arguments which you say are true are no longer true. Remember, that these arguments you provided have to be true for your arguments to work.
That is all there is to it, you either believe in Santa and alien abductions too, or you are dumb.
