I dislike that word because its usually used more lightly...like usually a quirk is seen as something that is a bit different or strange but doesn't really do any harm. So while I might use the term to describe some features about myself....I couldn't use it to describe my symptoms as in my mind it would be like downplaying them. Like 'oh its just a little quirk you have that when someone triggers you into fight or flight you have difficulties not punching them in the face' to me thats not a quirk that is a problem.

But I am not offended if people use the term quirk to describe themselves, just wouldn't want someone calling one of my severe symptoms a quirk as that seems to make light of it.
