You have a certain point, Jorge, but it isn't to do with mathematics.

You probably get frustrated reading posts from people enthusing about Bitcoin without knowing how it works.

So it's tempting to ask people, "Do you really know what you are talking about?"

But could I ask, at dinner parties are you in the habit of berating the person next to you because they don't know how credit card encryption works?

Although I suppose most people don't spend their time enthusing about credit cards at dinner parties - that would be pretty annoying.  

Still, if you have such a low opinion of Bitcoiners you are not obliged to spend so much time on Bitcointalk...
