Earlier quoted context omitted.
I think the battle is lost here already. I'm an educated native English speaker and I could literally care less if someone says "less" when, traditionally, "fewer" would have been used. It still annoys me that people describe things as "lite" instead of "light", but I realise the battle is lost as well.
I'm guessing you are from the US. I am from Australasia and the fewer/less distinction is largely respected in my experience. I find the example jarring. Regarding light/lite, I am doubtful that this is a problem outside of the US. Don't give in so easily!
I think I have some of this in my fridge right now. "Lite" is used here a lot.
I hear native English speakers in NZ make grammar mistakes here all the time. I'm really curious that you hear the less/fewer distinction adhered to.
