The guy was such an obsessive hater people even referenced him on trekweb.com forums
Obsessive haters pop up from now and then, that's normal, I guess... I know of long time posters who left certain forums because they couldn't cope with everyone around them not sharing their hate. It's like they were disappointed that so many people turned their backs on their one true messiah Gene Roddenberry. BTW, this happened both in 2001 (ENT) and in 2009 (ST XI). History literally repeated itself.
Also, people would occasionally register to a message board just to rant about ST being dead, then get permabanned for calling everyone who disagreed with them idiots.
And then, there are some who still fight the righteous war for the one true Star Trek, and don't mind getting mocked.
