Even with Lucas' anyone can learn the Force thing he still sticks to the idea that some people are inherently stronger in their connection to it than others:

The Skywalker line is very strong with the Force, so Ben says, “I think we should protect the kids, because they may be able to help us right the wrong that your husband has created in the universe.”

So while you could train others, they still wouldn't be a match for those that are naturally more attuned to it like the Emperor and Vader.

Which then makes the idea of anyone being able to learn it stupid because that's like saying "anyone can learn karate, but they have to stop at the brown belt, no matter how dedicated they are or how much they practise, because they don't have a strong enough connection to their chi" or whatever.

I just think it's a really dumb idea that either devalues the Force and characters connected to it, or it devalues itself as an idea.
