Dave1185 is just an insulting, rude editor. Look at the top of his homepage: 
"Vandals, trolls, and other fiendly visitors, please note: "Wikipedia is a community, not a crazy den of pigs!"
Social experimenters, please note: "We're an encyclopedia, not a bunch of lab rats in a cage.
I personally try to respect anyone and not to prejudice like Dave1185. That does not mean, that i am always forgiving. But even just using the ugly rudeness of himself against him several times did not stop him. A famous scientist (i currently don´t remember which) quoted: "You can´t overestimate the dumbness of manhood."
