Delhi is not exactly and wholly the real racist.
The thing is, this 'racist' crowd is usually the low IQ pre-independence migrants who upon arriving, got housing and lands for free, traded for decades in selling and buying houses and got rich. Now their generations have money but not the brains or education to know about our country's beautiful diversity and places and people.
SO these morons think that they own everything in Delhi. Now their good for nothing college-age kids have money to spend and enjoy materially but cannot get into a decent college while people from NE are either getting in through government allotment or through sheer hardwork and commitment. Many such jokers cannot digest others succeeding and hence they call names and attack.
Many times these hot headed idiots get beaten up in response too.
No.
We just tell you the facts on how it is dealt here, something which you cannot digest.
We certainly don't need fighter jets and troops to bomb own people.
Regionalism is a problem even in your home country and even in US (the so-called homogeneous culture).
But the point is how to deal with it and solve it.
Only social initiatives, awareness and legal methods can sort such concerns out.
And that is what is happening.
Nationalism is actually uniting people here faster than ever before. Education, better awareness of each other and slowly respecting each other is a part of every country's process and we are doing that.
About time Pakistan also learned it within. It will only bring peace to your kind.
