I have been involved with discussing the topic of the trinity, Nicene creed and early Christian history, yes. ..not because what other people believe bothers me, but because, much like @Thomas , I like to discuss the Bible and Qur'an .. faith in Almighty G-d. I can get frustrated in a discussion, naturally .. but that is not about being angry about somebody's beliefs. The Qur'an says that people who believe that Jesus is G-d are wrong. I am not G-d. People can believe it or not as they wish. I was raised as a "Nicene Christian". Was that my "fault" ? I don't think so. It is not for me to judge anybody else. It is for me to communicate with others, and encourage people to seek knowledge. If they don't want to, or think that I'm wrong, so be it.
