I understand the feeling of wanting to block out negative noise. A while ago I joined the Blender Artists forums, and posted some stuff from Radical Racer's Run. For reasons I cannot understand (perhaps because I mentioned my model was based off of an old computer game?), the first reply was "So what you are saying is that you didn't make anything?"
I was incensed! So I decided to quit Blender Artists immediately, never to return. I just don't need that skeptical of a community. I understand if CD5 feels the same about me, but I still look forward to seeing his machinima!
