I don’t care who you are and what the message is, no one likes to be preached to. Now I warn people that if they visit Freethunk they are going to get a fistful of opinions but then they are free to bite back and comment. When someone is preaching it is usually one-sided. I also find that people have to convince themselves of something and therefore if you’re too preachy you risk losing the argument. You need to make your arguments concise (something I’m often forgetting to do) and then steer people towards resources for their own study.
