Yes, absolutely.
Body language has an impact on intimidation, for example. It's not just a lack of respect that's conveyed by examples such as those just cited: using one's telephone when someone is speaking, talking to someone else nearby and not paying attention. People can also roll their eyes or cross their arms as they look at someone.
That doesn't amount to saying that we're weak. You have to recognize these things. We aren't stupid either. We know what intimidation is. Some people want to make a good impression by insisting they said nothing. However, it's obvious they did something: They wanted to communicate something by being disrespectful or exhibiting impatience, for example.
We haven't come here to tell people they shouldn't move their arms. I'm a francophone, so I obviously speak with my hands. Let's be realistic. We are adults, and we have to be realistic. When someone shows a lack of respect, we know what that is. However, we don't have the courage to put our foot down and say that's enough. Until we manage to do that, nothing will change and we'll keep going round in circles. I honestly think we don't have the courage to actually finish this discussion.
