Most of us would avoid eating poison no matter how good it initially tastes because of what harm it does to our body so why aren’t we as careful with what comes out of our mouth? If we don’t want another to react with venom then maybe we should be as careful of what comes out of our mouth then what we put in. A homeopathic doctor might give you a tiny bit of something that is detrimental to your health to allow your body to learn to understand and defend against this attacker maybe we should use the same tactic with the words that come out of our mouth. Being tactful doesn’t mean that you lose the freedom to control what comes out of your mouth it just means that every word has the desired impact for understanding and change that you seek. Poison hurts whether it’s swallowed or expelled for the person who takes it.
