So the rainbow is the symbol at represents the whole of humanity, regardless of race, colour, beliefs - or lack of them - and especially lifestyle; PROTIP: there have been straight people who have participated in Pride marches/festivals; like me, they're pro-LGBT.
D'you know what generates a rainbow, Lala(land)? When the sun appears after a rain shower, sunlight is refracted through tiny water droplets suspended in the air, creating a prism effect, light-splitting into the separate colours of the visual band of the electromagnetic spectrum. The optimum angle for said sunlight to enter these droplets, for said refraction to occur, generating said symbol of the oneness of humanity, with all it's differences?:
I wonder if Norway's fjords were designed - and won another award - by Slartibartfast again...?!
Now if you'll excuse me, Lala(land), after proving the nonexistence of God - which is infinitely easier - I'm just about to prove that black is white, via the use of this Zebra crossing.
...is that a car I hear approaching...?
