Great question. It depends on whether you're trying to accomplish humiliating someone, or genuinely correcting them. Here are my thoughts, based largely on experience in conversation with people of differing opinions. People do not respond well to aggressive language or posturing in a conversation; they will shut down and intentionally disagree with you. This is especially counterproductive when you pose a proposition to someone that requires their further pondering of the facts and circumstances. In stead of honestly trying to consider something you say, they will seek to find any information, whether trustworthy or not, or in context or not, that disagrees with you.To give you an example, yesterday someone asked the question "if the big bang is true, why is the Universe being pulled back together and not still expanding". Now, this question was based on an factually incorrect assumption (the universe has not stopped expanding, but rather, is expanding faster than previously calculated due to Dark Energy, only recently discovered). Instead of being arrogant or rude, I kindly corrected this person's information and posted a link to a humorous conversation between Jon Stewart and a popular Astrophysicist who, through the course of this televised interview, touched on that subject.Second, morality is an issue. You have to ask yourself to what standard to you seek to hold yourself and your moral compass; that is a question only you can answer.
