Fred, i think you're the one with reading comprehension problems here. Again, the whole point is that the sentence is unnecessary. Specifically the sentence you're referring to, because i in no way tried to handicap your ability to express your opinion. I did point out a flaw in your logic, and expressed an idea. Where did i tell you you shouldn't express your opinion?
You should definitely heed your own advice. Read things for what they are. Comprehend what you read. Think before you react.
