I agree with James. Teach your child the truth, that it is for no man to judge-find a quote from the scriptures to memorize, maybe put it in a simpler language. Whenever faced with the intolerance and prejudice she can run the scripture through her mind. Scripture is part of our armour.
But why dost thou judge thy brother? or why dost thou set at nought thy brother? for we shall all stand before the judgment seat of Christ.
Romans 14:10
Now it is better that a man should be judged of God than of man, for the judgments of God are always just, but the judgments of man are not always just. Mosiah 29:12
My heart aches for these wee-ones whose hearts and intentions are pure.
