To me the FLAT EARTH has TWO interpretations.
There are those that believe that the 'planetoid' is physically 'flat' and when Columbus was trying to convince his 'investors' that it wasn't, before he set sail ...he was afterall, standing on a giant 'flat' map of the world.
Then there are those like myself, who - kinda follow the 'Straight Way' as Tolkien imaginatively described it in his Novels. The 'Straight or Flat' existence is a 'Way of Life' and belief that adheres to the concept of ...lets just say, for argument's sake 'Western/Politics' being able to see 'forever' by having an expression around the world from USA, to Australia, to UK and thus can see around the world in all directions (you can quote a Biblical chapter on this as well).
So in essence, I can see beyond the curvature of the horizon and see also from the UK & USA ...politically.
It goes along with the saying:
A Scientist will say that the Earth is NOT the centre of the Universe and he/she is RIGHT.
A Spiritualist will say that the Earth is the centre of OUR Universe and he/she is 'also' RIGHT.
So for those who 'physically' think that the Earth is Flat, well - sorry dudes, but the Scientists are definitely right.
But for those who see the 'Straight (Flat) Way' of the World as an understanding and Enlightenment, then the Scientists will find their lack of common sense on this level found wanting in their endeavours.
