As the old wisdom decrees, opinions are like assholes; everybody has one, and they need to keep it to themselves. What old wisdom overlooks is the relief of letting it go and the satisfaction from dumping on somebody who was asking for it, after too long of holding your breath.
Opinions serve two important purposes, both as teaching tools for anyone wise enough (and brave enough) to learn to use them. They most commonly find roles as defensive tools, whether against someone we have offended, a teacher struggling to clarify a misunderstood point, a proselytizing predator howling at your heels, or anyone asserting something with which we disagree.
Even predators can learn by applying the second purpose toward the achievement of their own betterment. While the stings and burns of battle still rage and the heat of it still warms your brain, now is a good time to reflect on the process just undertaken, while still fresh in memory. Predator and intended prey will consider their answers for the same list of questions, plus some of their own:
Might I owe my opponent(s) an apology? Nobody will gain true knowledge from name calling, accusations, nor any other form of personal comments.
Did I engage in that to proselytize? —to exchange information? —to ask (a) question(s)?
Did I intend to learn something? —or tell something about which nobody asked?
We get poorly educated about rules for effective argument or thinking. Most of us have no idea why such topics should be hers as though we have the greatest expertise in that topic. Some may be, but why argue if you can’t convince, and will not learn.
