There is nothing to be gained by calling religious people hypocrites because they don't accept the same rational for the rejection of other Gods.
I think you're misconstruing what the argument is intended to mean. It's not usually offered to portray the religious as hypocrites; it's usually offered in response to a believer who says "I can't imagine/it's not possible to not believe in God."
In that case it's highly appropriate to point out, in reply, all of the various and sundry Gods that the speaker
already doesn't believe in.
