My feelings are that just disagreeing with someone has no apparent purpose ... There is a whole lot to disagree with, although an explanation would be necessary for clarity, I truly believe people can hold their tongue as opposed to just out right stating "Your Wrong!".
Long story short it's rude. But being inquisitive, or enlightening is fine. I think this all goes back to mama telling me if I don't have anything nice to say don't say it at all. Nobody likes an argument and nobody likes to be told they're wrong.
This is completely opposite to how I feel about it. I think a simple statement of "I disagree" is useful when someone is so offended by a post that they have to somehow note their disapproval, but starting a debate in that thread would cause disruption and throw it off topic. I think it's the opposite of rude. It's considerate to the OP and the original topic. If either party wants to elaborate or ask for clarification, that would be the time to PM or start a new thread on the topic of disagreement. I never once used the "disagree" button while it was in effect because I didn't feel strong disagreement over any posts. I would only use it if I were truly offended by the content of a post. However, I also see the potential for abuse of the option to disagree. Some people are far more easily offended than I.
