There are a lot of different types of "facts" out there, BB, and they vary wildly from one civilization and culture to another.

There are some we all can agree on, such as...

1 + 1 = 2
up is the opposite of down
things fall down, not up
water flows downward and takes the path of least resistance
etc...

Then there are some we don't agree on, such as...

The USA is the greatest nation in the world.
China is the greatest nation in the world.
Japan is the greatest nation in the world.
Russian is the greatest nation in the world.
Egypt is the greatest nation in the world.
etc...

Yet many Americans feel that to state "the USA is the greatest nation in the world" is to state a fact! ;-) Well, it's not a fact, it's an opinion.

When making political arguments, people sieze upon any fact(s) that they feel will strengthen their position, and they discount or ignore any fact(s) that they feel will imperil their position.

This has been going on ever since Og said it was a fact that Mog stole his wife and cheated him at "toss the sticks".

We will never succeed in all agreeing on which facts truly matter and which facts don't and which are really the REAL facts and which aren't.

So, get used to it. ;-)
