Some people are just die-hard critics. You can't avoid them, and you can't win them over, whether you try to spin the gospel to suit their tastes or you tell the truth and hope God will work in their hearts. They're not even looking for the truth. They just want to find everything wrong with Christ and Christianity, which is a tragic response. In the end, the truth will be justified by what it produces. And they may not know the truth until it's too late.
