I received some comments from someone claiming to be an Indian Christian1. I first thought that it was not worthy of a proper response, but after more thought I decided that unless the points are rebutted there is some chance of people might actually believe some of them to have merit. So here is what the poster had to say.
Writing this response seems somewhat surreal. I know so little about Hinduism compared to the many Indians that John must have met who could have pointed out his errors. I know that many extremist Christian groups tell their children not to talk to people outside their group, but I still find it surprising that he has not been informed more about Hinduism.
