I wouldnt let locrian bother you mate, hes not highly regarded outside of his own little world, let alone outside of the fpsc zone.
Another outburst from him will result in punishment he deserved a long time coming.
Anyone whos that negative must have issues they cant resolve, personally i wouldnt let it stress you.
Its obvious to the elders as well as anyone with a fabric of moral decency, that his outbursts stem from his in ability to think rationally and get along in social circles.
I have a charming email from him, when he decided to make racial comments towards another user and was told to pull his head in.
Let the mods handle those issues while you focus on your modeling.
