I am aware that anecdotes are not as good as large-scale evidence. That does not defeat the point that you are confusing necessary and sufficient conditions, rendering your own anecdotes even more useless than mine and @layer8.

Really weird that you keep insisting that you're right here. Some guy on the internet made a conjecture, other people disagreed with him, and you feel the need to keep boosting his claim. Yet every argument you make equally damages your own side, rather than showing that your side is stronger. Really weird approach.
