Don't be afraid of him

Deuteronomy 18:21, says, "And if thou say in thine heart, How shall we know the word which the LORD hath not spoken? 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." I thought this false prophet was going to die. Was he saying the man speaking falsely would eventually die of old age or something? I should also point out at this time (probably way too late), that the prophets are always refered to as a man. I understand that woman lead to the expulsion of the garden of Eden, but it has been how many generations and woman are still being treated as cattle. They can't even be false prophets. What's the deal? Why do any women believe in a religion that seems exclusive to man?
