Good intentions sometimes do not have good results.
Phidaissi... I think this sums up everything...
If no one tries to tell those with good intentions, then those results don't change.
I can't force anyone to change who they donate to, but I can try to educate them as to why their good intentions might not be having the good results they believe them to have.
The fact that people say they are 'sorry to hear' someone is autistic really says a lot about perceptions of autism, and that's really bad for autistics.
People with disabilities do not want pity. They want acceptance.
