It is about how one would take it with a grain of salt and to absorb it in and then rather being defensive.
Sure, We may have said things that were harsh or said things that were not meant to be. That is when one gets the emotional aspect into the play. When that comes hand in hand, it always results into a "blame" game. In this case, We are trying to understand what is the metaphor or the backbone of why hearing parents feels rejected by the deaf community or why a deaf person would feel rejected by the hearing community.
I'd say in overall, Responsibility plays a huge part in this but before they take the responsibility for it, one has to absorb it in. To be articulate, you'd also need to understand where both sides comes from. That is something that has always resulted in a battle between both communities. Respect is also a 2 way street. It takes two to tango and all that.
Before we can look at this as a group, we also must look at it as an individual issue because how can we find the middle ground of this when we are looking at a group alone? I think in order to understand how this flaw can be worked out is by looking at an individual to bypass it and after that, we can also work on the group. United we stand, Divided we fall.
