I don't really see it as any hate. For general use, a fixed bike simply isn't as easy to use/safe for most people. I think that's all he's trying to say, and it's a valid point.
The inability to freewheel is a handicap for most people, especially casual riders, or anybody who has experienced an unusually tiresome day. Stating that isn't professing one's hate for the breed, it's just the truth.
