The last half is basically his own opinions stated as truth from God, which, to me, makes him look like a complete tool. Personally I'm not a fan of parens around the conditional in ifs, but I don't go around spouting that it is the only true way.

It basically makes me write off the first half, even if it is correct (I'm not a linux dev, so I don't know).

Added: From the reply on lkml I'm not the only one.
