The end of the year

It always seems to me that I become aware of stuff at the end of the school year. So C is suppose to be a part of a regular ed classroom for part of the day. I think I have mentioned that the district I teach in is an all inclusion district which means that special ed kids are part of the general ed class FIRST. They go to their special ed class for the areas that they need but do all special classes,lunch,recess,field trips,special programs,etc with the gen ed class. At C's school,that is not the case. His special ed class is a class by itself with it's own specials schedule,lunch,etc. So sometimes he is with the gen ed class for special things,etc but not all the time. So his gen ed class is doing a wax museum that he is not a part of . On a field trip I volunteered to be a chaperone and only had C in a group. The other special ed kids were all by themselves too (with a couple of teaching assistants,but not with any gen ed kids). His reproductive health homework was for me to sign a sheet saying we talked about it. He told me the special ed kids did not need to do it. (I'm not sure if that is his words or what the teacher said). So in a nutshell,I'm pissed.
Here's the thing,I know C is different. I came to that conclusion many years ago. But,seriously,throw me a bone! Let us think that for a minute,he is just like everybody else. Give him a speaking part in the play. He won't be as good as the regular kid but when he is up there,saying his part,he will be a regular kid (to me anyway). Give him the homework everybody else is getting and then wait for my email that says."this homework is too hard." or "he verbally told us the answers and we wrote them down for him." If I volunteer to go on a field trip it is not because I want to spend time alone with my kid (I do that every day) but I want to see how he interacts with his peers but most importantly how they interact with him.
I am having a hard time understanding how people can not see this the way I do. What is so hard about knowing that someone is "behind" or "not up to par with their peers" which is fine because we are all at different levels in our abilities. What is so hard about understanding that everybody has FEELINGS? and that when they are excluded in any way,shape,or form they feel bad. What is so hard about that?
