You cannot control how others perceive you. They may gain an unfair impression of you and once you are diminished in their eyes, you may never overcome that deficit. Is it fair then to have that same rigidity in your own thought?
One important thing is not to frighten people or to belittle them. If you come across as too aggressive in your ideas or continue to belabor the point, then you can appear to be mean or uncaring.
If someone is intellectually cornered and they are then threatened further, then you will ruin any future rapport you may have with them.
Do you chat with everyone you meet at work for a minute or two? Do you make it a point to stay after meetings to listen to people? Do you ask a lot of questions and listen to the answers and look at the facial emotions during the response? Of others in the room when you talk or others talk? Do you ask others opinions and can you see the merit in their ideas?
