Code:
dis·dain
/disˈdān/
noun
the feeling that someone or something is unworthy of one's consideration or respect;
contempt.
"her upper lip curled in disdain"
Nope - still not disdain. Frustration is still more accurate.
IF we felt disdain - it wouldn't be worth our time or effort to even respond to those threads.....
Smiley faces are there specifically to give that non-verbal communication that is missing in the typed correspondence. Thus converting something that could be mistakenly taken in one manner, and portraying it in the way it's intended.
