Before we get into the realms of moderation
There are differences in points of view in this hobby. Maybe someone is wrong or uninformed in your books but is doing what they feel is correct based on the knowledge they have. It goes both ways, challenging the accepted norms can move the hobby forward but it also comes with risks. Those risks affect other living things, and not just the wallet. Be on your toes and be prepared if your method does not work out.
