Sometimes it goes like this : here I was answering to someone who was convinced to be absolutely right and I'm still quite believing the opposite.
I don't know how to put things straight in these occasions without using some quite radical speech and this may look like being a cunt.
You may be right : I'm putting too much energy in this thread, especially considering all the downvotes. But I did put much much more energy during many years reading useless scientific article on this topic, leading to nowhere and I'm hoping someone could at last prove this to be useful.
