All of this. There seems to be a perception among many people that disabled people have special privileges lavished on them and seem to regard the few concessions made to the disabled as 'perks'. When in reality, just living our lives present barriers that would not be considered acceptable for any other minority group.
Just a few very recent ones (I have 100s I could refer to):
I organised a hotel stay for the family recently including DS. The hotel was 'traditional' and not accessible for wheelchairs. So the rest of the family were accommodated in the historical building whereas we had to stay in the soulless 1960s annexe and have a chilly walk to the main building for breakfast every day. As the grand entrance had steps to it, unlike the other paying customers we had to use the tradesmen's entrance at the back.
We were invited to join a show with other friends/family members. We couldn't go because most of the wheelchair spaces were sold and the remaining ones were in places where we would have had to sit DS with one companion, which would defeat the purpose of attending a show with friends/family members. So unless things are planned far in advance with military precision, we can't take part.
And just today: we got a bus home from a day out. The wheelchair space was occupied by a child in the buggy which was not moved by the parent so we had to make do; even though it is clearly stated that the space needs to be cleared if needed by a wheelchair user. This happens all the time, it is actually very rare that the space is cleared for DS. I have the wretched choice of arguing with the parent to move the space (not what I want to do after a nice day out and in front of DS and children), or just letting it go and instead feeling I have let DS down by not standing up for him.
I agree with other posters that notions of 'accessibility' and 'inclusivity' have led people to believe that all this is acceptable.
