Well, I can understand that frustration, September. I also know that we can't control others or assume about their actions and thoughts (not saying you are...just saying).
Remember the analogy of the rope? There's no resistance if it's not being pulled from both ends. If you find a resistance has creeped up on it, drop the rope and the tension gone.

Of course, that doesn't mean that you can't make use of the parts of the rope where there's no tension.
In other words, we can only control our own experiences and a good way to do that is respond to what is positive for us, not feeding a debate where it's not an agreed upon action in a discussion, remembering that response in furthering our position is a continuation of an argument where one exists.
A good response might be, "Thank you for your thoughts," and that's that (releasing our tension on the rope), ya know?
Love,
Kim
