I support everyone's rights to be whatever they want to be, whatever colour their skin is, wherever they were born, wherever their parents were born.
They can like cricket or rugby. They can be gay or straight. They can eat curry or roast dinners. They can marry white girls, black girls or anyone.
They can wear red trousers or a ****ing skirt for all I care.
I don't think it's anything to do with being ashamed; I think it should be celebrated that people from different backgrounds or even from the SAME background have a choice over how to live their life and just because YOU make a different choice it doesn't mean they are 'ashamed' and you are 'proud'.
There is a real problem with people being ashamed of their ethnicity/culture for various reasons but an Indian guy wearing red trousers and drinking Pimms really isn't a big ****ing deal.
Just let people do whatever the **** they want, quit judging them, and lose the superiority complex.
