The problem with using Holocaust images or the word "Holocaust" too broadly is that there are many people still living who survived the Nazi death camps, or whose parents were survivors, and they would be offended.  It might result in more opposition to AFF and the autistic civil rights movement.

I'm not saying the comparison shouldn't be made, but the words and images will have to be carefully chosen.  There have been other instances of genocide at various times in history, and it may be more effective to use language that is not specific to the Nazi era.
