Oh by the way, I am more than happy to hear what you have to say against mormons. Bring it on. You will be sorely confounded. There is not one single apparent contradiction you can come with. You had better come strong.
Of course the Bible warns about false prophets. Like I never heard that one before

Before you go pretending to believe in God, you had better brush up on your scriptures.
Num 12:6 And he said, Hear now my words: If there be a prophet among you, I the LORD will make myself known unto him in a vision, and will speak unto him in a dream. Both Happened to Joseph Smith..... wait I can already hear it coming. You don't like old testament scriptures. ok fine.
Deu 18:22 When a prophet speaketh in the name of the LORD, if the thing follow not, nor come to pass, that is the thing which the LORD hath not spoken, but the prophet hath spoken it presumptuously: thou shalt not be afraid of him.....
Sorry, couldn't help that last one. Here's the new testament ones:
Mat 7:15 Beware of false prophets, which come to you in sheep's clothing, but inwardly they are ravening wolves.
Mat 7:16 Ye shall know them by their fruits. Do men gather grapes of thorns, or figs of thistles?
Mat 7:17 Even so every good tree bringeth forth good fruit; but a corrupt tree bringeth forth evil fruit.
Mat 7:18 A good tree cannot bring forth evil fruit, neither can a corrupt tree bring forth good fruit.
Mat 7:19 Every tree that bringeth not forth good fruit is hewn down, and cast into the fire.
Mat 7:20 Wherefore by their fruits ye shall know them.
Better bone up before deal with someone who knows

their scriptures.
Give up now and admit you don't believe in God.
And for Mr. Hello Kitty. Just because you are mad at the church doesn't mean you have to smear and lie about them.
