Totally agree, except one thing; that last part. It does something; it makes things worse by keeping silent. As you already kinda said, with the unproductive part.
Some might chuck it down to a long run, false sentiment or whatever, but for me this topic has close connections to the meaning of dates of this week to my country. Yesterday we celebrated the country being liberated from WW2. The eve before that we remembered all those that have fallen in WW2 and any war situation since. Very sobering days.
As some might know, I'm Dutch. Part of our dark bit of history during WW2 was our way of thinking and acting. Don't see anything, don't hear anything and just follow whatever the Nazis would come up with and keep your head down and only worry about yourself. It started small enough, administrating all of the Jews. We all know how WW2 would end up. Because of how we as a Dutch nation -both individuals and gouvernment workers- acted the Nazis were able to murder a higher percentage of Jews, gypsies, gay, resistance workers and indeed; disabled than in countries where that "see nothing, hear nothing, say nothing" motto was not the norm. One huge lesson to be learned, not just by us Dutch. Each and every day again. Society is not others being responsible. Me deciding to hear, see and say nothing is me also ducking my responsibility.
While today we are "only" talking about making and keeping something as luxerious as a visit to WDW possible to as many people as possible, the same lessons can be applied. Not speaking up is always worse then speaking up in a reasonable, respectfull way. Not speaking up will not make a problem disappear but it will give it room to grow. To become a poison eventually. We see things happen, hear things, know things. Those things can be used as a huge strength in a positive way. Not speaking out of fear, it's a much more scary option for me.
Sorry to drag such a heavy topic into this, but it's been on my mind for over a week. Seeing some patterns, differences and lessons that can be learned from that when it comes to how disabled are viewed and what their role in society is in general and more specific; how the group itself influences that, roles that can be had etc. This topic being opened I guess was the last drop for me posting it in showing a bit of where my sentiment on this comes from. *getting of my soapbox now*
