Gentlemen,
if you can't be civil and have a productive conversation about a topic, then don't participate at all. Everybody has an opinion and deserves respect even when you disagree. It is possible to disagree without personally attacking people and without being rude or judgmental. A good way to do that is to start with, "I disagree because..."
If the personal attacks continue, the thread will be closed and moderators will consider giving infractions or vacations to users who have violated the RCU community standards.
