I agree but I am a firm believer that all things between people are highly situational, including when to inform, when to explain, when to suggest, when to ask, and when to listen. Correcting people can be considered impolite. In discussions marked by conflict, it's often more useful to get the other person to arrive at your conclusion themselves, by simply presenting the information and your evaluation of its meaning. It depends a lot upon the audience, the prior conversation, the circumstances etc. People are marked by a great deal of hysteresis (not to be confused with hysteria lol).

It becomes tiresome to always phrase things with "I believe" or "my opinion".
