"Not that I recommend dispensing with a user account, but I have no user account even on my Ubuntu system."

This guy is an arrogant ignorant (which is the worst combination, ever).

Even distributions with root active (I used to use mandrake 12 years ago) discourage users from running everything as root because it is dangerous. Mandrake had a big warning and a red background whenever running X as root. If you run firefox as root on a regular basis you might get bad surprises, from all the kind of scripts that get executred. I am not one of these no-root paranoid. I am not scared of knives but I do not walk with a knife pointing at my chest on a crowded subway train.

 What I find unacceptable is that this guy is ignorant, has bad practices, dispenses bad suggestion, and does it with so much arrogance. No way!
