Yes, put plain and simply: words matter. For online forums (of any kind), it equates to not being a jerk or hostile in responses since vocal intonation, facial expressions, and the like are neither seen nor readily apparent between the sender and the intended recipient. Thus, the words chosen, along with the sentence structure used, could quickly lead to (unintended) miscommunication (on either end). Therefore, let’s choose our words wisely, ensuring we remain open to proper dialogue. Otherwise, just keep our thoughts to ourselves. Along the same lines of the Bible quote, I saw this very recently and copied it down: “before you speak, ask yourself: is it kind, is it necessary, is it true, does it improve upon the silence?”
