Proselytize often comes with a negative connotation. I have my own opinion, based on what I have seen as facts, which I have presented. Most of the time strange and impossible ideas(such as women's equality, "child abuse", and the civil integration of the races in States) appears like "shouting nonsense to the masses from the mountain tops". You're either preaching to the choir, or talking to people who'd like to stick you the middle just for daring to bring up the subject and strongly express a contrary view.
People often feel personally judged when something they do and believe in is questioned. I've never seen people not get offended on the topic of spanking, no matter how they presented it. It's all touchy indeed.
