ditto LigH. Typically when two words are used together, one is modifying the other. Thus, hurtful criticism means the type of criticism meant to hurt. If Dramborleg had meant all criticism, he would have said "criticism." Use le brains guys, come on.
Also, Sarras I guess you have a char ban not a player ban, as I saw your alt Merjer ig the other day. Hard to stay away from Yliakum, non? Also, if you study art with professional artists (professors and working artists) as well as reading about art, you would know that there are all kinds of artists in the world - many brilliant artists neither needed nor desired criticsim, as they self-regulated. Many others would have been lost without it. Better not to generalize about a group of people, displays ignorance.
Agree with Dramborleg. And love the initial advice (especially the monty python advice). For those who've never noticed hurtful criticism, keep calm and carry on (to another thread).
