Re: Not right in the head
"And can't you see what's wrong with that? Spastic is the correct medical term for those suffering with various muscle related illnesses, and yet because the term was used in a derogatory fashion, it's original usage is now frowned upon."
I agree there is nothing wrong with the words: spastic, dyke, black. It is there use in a derogatory fashion that is the problem. It is similar to marketing, if you repeat these words often enough in a negative or mocking connotation then their use becomes associated this that negative connotation.
The solution is quite simple: do not use religion/race/disability, or in this case, medical conditions as derogatory term. It would have been easy to use "badly behaved" / "annoying" / "offensive" in this circumstance.
In using the medical term in this circumstance you are causing discomfort to those people that have this condition and also those people that have a relative with this condition.
