Don't knock passion
Linus is a man of passion, a man through whom we have the best operating system on the planet.
I employ coders and techies. In the most part, they're lazy and cut corners unless you let them know exactly how bad it will get if they screw up. There's no excuse for sloppiness or laziness, and in an environment where so many systems rely on robust, well tested, well thought out and well written code, Everything from your laptop to nuclear power stations rely on gatekeepers who look after the quality that is produced by the varied bunch of programmers who, lets face it, are everything from quiet geniuses to unwashed pillocks who should not be allowed to code a pong game...
Politeness has its place, of course, but if someone produces sh*t they should expect sh*t in return... that's life, deal with it, improve your code and whine less, and everyone will be happy!
