Exactly. There is a huge difference in the following two statements:
1. "I hear you about X but we are doing Y anyway."
2. "I hear you about X and understand you viewpoint, however we need to go with Y because..."
I'm okay with #2. #1 will drive me away. And it should. It's disrespectful and basically tells the other person that you have no regard for their opinion and that you only ask to satisfy a rule or expectation. If you are aren't going to have a discussion about why Y is the solution and were going to do it regardless of what anyone else said, then why bother even asking?
