We judge others instantly by their clothes, their cars, their appearance, their race, their education, their social status. The list is endless. What gets me is that most people decide who another person is before they have even spoken to them. What's even worse is that these same people decide who someone else is, and don't even know who they are themselves.
It's okay to disagree with the thoughts or opinions expressed by other people. That doesn't give you the right to deny any sense they might make. Nor does it give you a right to accuse someone of poorly expressing their beliefs just because you don't like what they are saying. Learn to recognize good writing when you read it, even if it means overcoming your pride and opening your mind beyond what is comfortable.
