Spreading the truth Is good, more people should be exposed to the truth, but not when it means endangering anyone. Telling the truth to a person who can physically harm you is obviously not a good idea, that's why we have the internet! Although if you happen to find a friend who is perhaps an atheist and is open-minded, then by all means make an effort, but use caution and common sense. Satan wants as many people on his side as he can, but he also wants all of our safety, this is why it is advised to use caution.
