Why are people so subtly mean on Quora?

Answer by Karen Tiede:

Maybe they simply see themselves as blunt, or honest, or straightforward.

Someone–you?–challenged one of my answers recently.  "Do you really think that's an appropriate thing to say?" 

"Yes, I do," I replied, and left it at that.

I am not one to coddle.  I am not "mean," at least in my own mind, and at the same time, I am not one to coddle, to swaddle, to wrap up in cotton.

Dump the deadbeat, get rid of the GF whose causing problems, quit drinking, get a better job.  Why beat around the bush?

One Quoran's "kind" is another Quoran's "obfuscation."
