The "Otherization" of certain individuals/groups of people

[loyalsister]

8. One group you didn't mention is disabled people

You did mention that mental illness is used to otherize people who commit crimes. There was an immediate attempt to further otherize Trayvon Martin by claiming he used drugs.
Disability has been used as a means of justifying inequality by adding it to another difference. Women are naturally disabled because of biological processes. "Drapetomania" caused slaves to run away. Dysaesthesia Aethiopis led to the desire to avoid work.
Then there was the argument that slavery protected people from disability.
Just a little more food for thought...
