How do you deal with it? DO you tell the other child's parents that you strongly disagree with their point of view? Do try to stop your child being friends with the other child? Or do you think that what the parents believe and have as their point of view is their business and let the children be friends with whoever they like? Does it make any difference how old the children are? DO you think it reflects on your family if your child is friends with a family that have unpopular viewpoints?
