I'm adamantly opposed to proselytizing. There are 91 different names for God in the Bible. I take that to mean that there are multiple ways of thinking of God, of connecting to His teachings. Different paths, same destination. With the advent of the Internet we've been given the gift of information at our fingertips. Telling another or even suggesting that their way of believing is wrong is to attack their identity, their very essence. There's another group who proselytize whom I find just as objectionable: Atheists. From the New Atheists to Militant Atheists.
