Does Disability Lead to Arrogance?

I have been working with a few hard of hearing individuals lately and it has been cause for some frustration. I cannot believe the arrogance and rudeness that I am experiencing. Two in particular choose not to listen to each other, constantly talk over one another and are just generally rude. It feels as though both are struggling for dominance within the committee instead of just working together. The goal of this committee is to help the hard of hearing, and in the end it feels like they are losing sight of that.

I can't help but think that over their years working with hearing individuals they have had to push and in some cases be assertive and hard nosed to get their voice heard. Both have been extremely successful in achieving results for their causes but I wonder if their drive and their disability are leading to this arrogance. On top of that, I wonder if this arrogance is just a cover for their insecurities.

Regardless of the root cause of their behaviour they need to see that it's not productive and it makes working on a committee with them extremely difficult and frustrating. I would think that individuals who understand the importance of listening closely and paying attention would show more respect when another hard of hearing person is speaking. Again, we are all working together for the same end goal, there is no need to step all over each other.
