By speaking openly about your beliefs and opinions, you subject yourself to criticism. This goes for anyone. Rather than criticizing or putting someone in a category, really listen… then respectfully reply. If you agree then great. If you disagree then discuss. You may not be able to 100% logically defend your position, but that’s okay. It shouldn’t warrant rebuke or disfavor.
These discussions are better had face-to-face where the human element cannot be overlooked. These discussion can create a new or deeper understanding. But remember, there is nothing new under the sun.
