Have respect for other opinions. If you disagree with someone, do not attack them personally. Try to make thoughtful comments about their opinion, perspective, assumptions, etc., but do not attack them personally. Everyone has an opinion based on a number of different factors, like their own personal experiences, values, etc. If someone disagrees with you, it is probably because they value one thing more than another. Attacking them does nothing but create anger and resentment. Discussing the values and perspective that underlies their opinions may increase your understanding and it may encourage them to see your perspective as well. Personal attacks are the tools of someone who probably doesn’t have a very good point to make, or of someone who holds a belief that has no foundation in reasoned thought.
