I don't think this is quite fair, explanatory examples can be very helpful at cementing the point or persuading the doubtful.
What does shit me is the amount of 300+ page books that have at least 50-100 pages of unnecessary fluff. Giving 1 story or example to illustrate your point is one thing, but stacking 4-5 dull dull DULL stories is just a chore to get through.
