What other interests do you have apart from Chess?

Lack of critical thinking skills. Truth is not the same as existing. The belief that the sun revolved around the world existed. However, that does not mean that it did.

Nazism was VERY fashionable in Germany decades ago. Does that make it true?????

Not sure you are asking what you think you are asking.

Logically speaking, Nazism is true because it existed.

I think you've finally let the worms eat into your brain.

So you are saying that if you believe something (the belief exists) it must be the truth?????

19th century?

Sure. 

It was just that he ased if 'Nazism is true?'. Which, as you pointed out, it cannot be true or false.

However, I am a programmer. And, in programming, if something exists, it is considered 'true'. 

Perhaps I should have put that in there somewhere.

Watching football, reading literature, video games and learning languages/cultures

Nazism was false. The Jews are not sub human and there is not a worldwide Jewish conspiracy.

There is no such thing as a 'valid' or 'invalid' world view. A world view is shaped by the experience of the person creating it.

Perhaps when you say 'true' you are meaning 'truth'. These are not the same thing.

One can prove Nazism false with empirical data.

One can prove Nazism false. Simply prove that Jews are not subhuman and that there is no conspiracy. Similarly, scientology can be proven false. Simply test there machine and see if it reads minds.

"true" "false"

True, definition #1 - in accordance with fact or reality.

You are confusing validity with truth.

Here is an argument that is true and valid.

1. Socrates was a man.

2. All men are mortal.

3. Therefore Socrates was mortal.

Here is an argument that is valid and not true.

1. All Martains eat snakes.

2. Bob is a Martain.

3. Therefore, Bob eats snakes.

Here isan argument that is invalid but true.

1. Nixon was peesident.

2. Eisenhower was president.

3. Therefore, Carter was president.

Agreed! Nazism isnot true because it does not correspond to the facts. Jews are not subhuman and there is no worldwide Jewish conspiracy.

Nazism was real, it is a fact. 

This is not the same as saying it was correct.

Again, truth/correct are NOT the same thing as 'true'.

I would say that Nazism is valid (its beliefs follow logically ). However, it is not true ( its propositions do not correspond to reality).

This is one of the great thing for philosophers, even amateur ones, you can say anything in any way you want even when it falls outside the bounds of reason and still feel you are correct.

You're trapped in the minds of madmen my friend.

Nazism is a belief system. Beliefs (propositions ) can be true or false. To say that because a belief (or proposition) exists it must be true is silly.

So your belief that all propositions are true is not madness????

Note that your lack of philosophical reasoning ability has made you accept an insane proposition, that all propositions are true.
