Avira, the speaker was making a point worth thinking into. Perhaps it was too broadly stated, or quoted. Like every statement, if you don’t preface it with 10 introductions about exceptions and what you don’t mean, you’ll have people pointing out how wrong you are because of the areas in which your point doesn’t apply.
Get real. Listen to the actual point, and apply as fit. Especially, when the point is not the topic being discussed.
