@ippiki_ookami:

Honestly, if an artist is going to take their ball and go home over legitimate criticism regarding their art... well...

Really, the artist is only shooting themselves in the foot.

@TheTundraTerror: I didn't know legitimate criticism has to come in the form of belittling, personal attacks, and insults.

Just because something isn't breaking any rules doesn't mean it's in good taste.
