"Well wikipedia banned me again. Its been an interesting study in totalitarianism, it is clear to me now that even a "benevolent totalitarianism" is to be avoided. It is often argued that anarchism is to be avoided due to "mob rule" but in fact totalitarianism is just that "mob rule", anarchism is really an overthrow of that mob rule and an insistnce on equal rights, something which wikipedia refuses to accept. I guess that's their right, it's a shame that so many people are unwilling to even attempt to discuss their issues. I guess Ill go back to studying chess."
"unwilling to even attempt to discuss their issues" -- I got a chuckle out of that one -- since that's all we do, some days.. discuss our issues. :-)
Since Adam [name omitted for privacy reasons] was never unbanned, the "banned me again" arguably refers to the Vera Cruz banning decision.
Those interested in the level of intellect that we are losing (high? low? you decide) by banning this person should review: http://qwert.diaryland.com/older.html
