@A Vestigial Mote: Very good point. Thank you. Suppose you believe in the "Cringies". If that's a real belief for you then it is true for you. If you are convincing enough it will be true for me also. If you only make it up to proof a point then you don't belief in it yourself. So it's not a truth for you. You won't be too convincing, so won't be a truth for me also.
Few examples I came across:
1): I was in a bus, 10year old kid says to driver "run over that cat, we get points for that". True story, this kid was still in his mind in the video games. For him it was real. Quite scary.
2): Same with brainwashed IS fighters (incl. kids). In their minds its real.
3): I talked to a minister. He was so convinced that his Baptist way was the only truth and all others goto hell. He is not stupid, 60years, photographic memory, medal of honour by Dutch King. For him it was the ultimate truth. He was not aware of being disrespectful as explained below. That's all.
Living in this world, our feeling have a kind of truth in them; at least for ourselves. So that's why it's a kind of truth (not the ultimate, universal truth)
So if you use these 2 lines you don't respect the feeling of the other (tell him his feelings are not true)
God exist = True
God exist = False
But if you use these 2 lines you do respect the feeling of the other
I believe "God exist = True"
I believe "God exist = False"
I think this sums it up, and makes it much clearer then I tried before
