Have you considered that maybe most of the posters on this website weren't born yesterday and have also spent a lifetime absorbing facts from many sources and experiences?

In fact most people have, in some way.

But what is your point? Can't one come to a world view that is vastly different from his contemporaries?

Most of the posters in this website are teenagers or in their early twenties. Let’s not be delusional here, this is still the internet.
