I took this very negatively. Saying "that's not true" about a belief that is older than Greek itself isn't very nice. Many do believe that the soul is life. I do. And you're telling me a spiritual belief of mine is "not true". And how, pray tell, do you know you're idea is "true" and mine is false?
The soul is much more complicated than simply life force but it is at the core of it in my and many many beliefs.
