Yes Pakistani's are much more pale than Indians,whether its North,South,East or West Indians. Actually there is no colour much colour difference between a Indians whether they come from North,South. East or West.
Most West,East and South Indians are brown,North Indians are brown too but they are a little obsessed with fair colour so they proclaim them as white.So every Indian is brown in colour and you guys are same but there is just a little difference in tone that's all. Pakistanis are also brown,they are not white anyway. Anyway Indians are much more brown.
Anyway the more pale you are the less acceptance you get in the modern world...Tan is much more accepted now.
Well south india and sri lanka are much closer to the equator than are pakistan and north india...so naturally, when it is so hot, your skin gets darker to protect it from the damages from strong ultraviolet rays. Also, your skin gets lighter as you get farther and farther from the equator because of the deficiency of vitamin d in the atmosphere and when your skin is lighter it is better equipped to absorb whatever vitamin d there may be in the atmosphere. While in the hotter climates, there is a plethora of vitamin d due to the excessive exposure to sunlight and even though dark skin blocks the absorption of some vitamin d, it already gets plenty by being in the hot sun.
Also another important point: these changes in skin tone happen gradually. If an indian moved to a cold climate such as the northeastern united states or northern europe, an indian would not instantly become white skinned comparable to the europeans. However, if an indian's family lived in northern europe or the northeastern usa for generations, eventually, their skin tone will become gradually lighter because of the less exposure to sun light there.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
