Strangers and loving everyone

First of all Jesus didn't teach that we are to love everyone. He said we were to love our neighbors and then he gave an example of exactly who is our neighbor. People that are friendly with us, willing to share with us and help us are our neighbors. Anyone that doesn't treat us right are not our neighbors. Jesus said we should pray for the ones that wrongfully use us but he did not say we were to love them. We must teach our children the truth about some people. There are people they should fear.

I don't see you have a problem on the issue of strangers - the possible risks have been massively exaggerated by the media to sell newspapers - they are tiny. Your child is far more likely to get run over than abducted or otherwise affected by strangers. Your child will however become shy and scared of talking to new people and potentially struggle to make friends - that is the real risk of scaring kids away from strangers. It is far better to teach kids the different types of love and bring them up to be self-confident and able to be aware of risks.
