God loves you. Satan not so much. Satan knows where it's going along with it's angel's and will deceive, kill, and destroy. I'd rather inundate you with what you do not like if it is Godly versus give you any chance of indulging Satan in any way. Take it as an act of friendship/ kindness versus and act of hate.
At this point, me just doing nothing would have been horrible since I KNOW what is good and right versus just calling you a name or something.... (I do not mind rubbing and teasing you with God.) (He will never hurt you but it is up to you to accept or reject him.)
I'd have never sent you a Satan emblem as that would be active hostility as Satan is evil (I rarely use that word.). If I did anything, it was not to disturb but hopefully get your thinking changed. I won't apologize for bringing a nicety to you even though you stated you disliked it. I KNOW it wouldn't hurt you in any event BUT may in some way change your thinking to good things... Take care...
