Food for "reasoned" consideration:

""Opinions are usually based on a set of assumptions that are likely unique to the individual. Even though you may be sure of it, your opinion that you are right, and the other person is wrong may really be a reflection of your bias, views and values rather than an objective assessment of the other perspective.

Some issues are objective and others are subjective- it's possible you're right provided you have observable, objective facts. That's not the case with subjective issues.

Regardless, why is it necessary to change someone's mind on an issue?

Why waste your time when it is clear that the point of the discussion is not up for objectivity and what is discussed doesn't matter to anyone involved?

Debates are often respectful, interesting and fun, when it is not so, why waste your time?

Just because you know you're right it doesn't mean getting into an actual argument is worth it. Sometimes, it's best to just let it go and agree to disagree. ""
