Fair

I personally don't have a problem with people believing that fair people are better looking than darker people, or that thin people are better looking than fat people. I don't consider that racist. Everybody has a right to have their personal definition of beauty. Their life is their problem.
There was a time when I thought that this obsession was since the 'Goras' rule but further probe/thought leads me to believe that the obsession has sustained since ages. Ancient Hindu scriptures and modern poetry praise women endowed with skin "cast out of white marble". It is more cultural than anything else.
What makes sense to me is the explanation about the color discrimination that I read someplace which loosely translates to the following -
"Throughout Asia, dark skin is identified with the toil and sweat of hard labor in the fields, while fair skin is associated with an upscale lifestyle."
Problem begins when somebody pressures others into changing their lifestyle based on a personal sense of beauty.
The fetish has always been unfair on the Indian woman. Thankfully, intelligence and sense of humor don't have a color. And like your skin, you're born with them.
