I’m very disappointed in poem_for_your_sprog for almost understanding this point, and then immediately making the same mistake she was calling out
‘I have to sort my books!’ she cried,
With self-indulgent glee;
With senseless,narcissisticpride:
‘I’m just so OCD!’
‘How random, guys!’ I smiled and said,
Then left without a peep -
And washed my hands until they bled,
And cried myself to sleep.

Y’all need to learn that describing diagnoses by their symptoms isn’t necessarily better or helpful.
Y’all need to learn that psychology is a science which has only recently been getting it’s time in the limelight and you shouldn’t be offended by its terms becoming more common knowledge.
Y’all need to learn that your pet peeves don’t dictate how others must communicate.
Y’all need to learn that if misuse of language annoys you then educate rather than denigrate is always a better approach.
