I think stoning anyone to death for any reason is wrong.So I think your god is evil if it demands such punishment,or your the one who's gona throw the stone first?
But, since you think you opinion on this is totally subjective, what does it matter? If subjective, even saying 'god is evil' means nothing. All you are saying is that you object to it in the same way someone might object to a flavor of ice cream that he does not like.
