Can men be trusted with kids?

Me and my 5 year old daughter were watching CSI and the episode was about men abducting little girls, I had no idea how much it effected her, I didn't think much about it, thinking that she was old enough to know that it was just a show, until today her male teacher had called and said that she was going around her clroom saying that men were rapists and that they couldnt be trusted and another little girl got up and had pushed my daughter I guess in defense of her daddy, today is Friday and tomorrow she is supposed to go to her dads but she said she doesn't want to go and now my ex husband is claiming that he will try to get full custody of her and tell the courts I am trying to turn our daughter against him, but she won't even go around her older brother and wants to sleep in my bed, HELP SHE IS ONLY 5 YEARS OLD and I dont want her growing up thinking that all men are pedos and rapists
