You can never stop people from talking bad and negative stuff against and about you; but, you can always make them eat whatever they said, by living a good and exemplary life proving them totally wrong. Remember, God has not made anyone to depend on anyone for a living, as long as they seek, honor and worship God. It is just our ignorance and misunderstanding, that's all. Wisdom is what God gives to anyone; to begin with, when they believe and obey Him. So listen, learn, understand and change; to prove those bad guys wrong, by living an extraordinary, great life.
