Why are we so different from others?

One week back 9 black people were killed in a church in South Carolina in the US by a white young man, called Dylann Roof. Even 150 years after losing the civil war South Carolina has still not reconciled itself to the loss of slavery and flies the Confederate Flag in front of the state capitol to this day. Even after the shooting 8 lawmakers supported the flag as part of their history. They cannot see that it is precisely because of the their history of slavery, that this flag represents, it must be consigned to a dustbin. Although Barack Obama is half black the Republicans have not accepted his election as president and have opposed every measure he has proposed. Whites in the south of the US vote 85-90% for the Republicans. They will not expand Medicaid, funded by Washington, because blacks will benefit. But then 93% of African Americans voted for Obama in 2012. Is that racism or is it just a manifestation of black pride after centuries of oppression? Is it only whites that select friends based on color while blacks are color blind? Apparently not as these photographs of young British football players show. Black players eat at a separate table, exercise together and congregate together in the swimming pool. They were probably all born in Britain, all speak in similar accents and went to mixed schools in arguably the most politically correct country in the world. Perhaps it is instinctive, in that we find comfort in those who look like us. After all the first faces we see after birth are those of our families and maybe that memory stays with us for the rest of our lives. Or are their genetic differences among groups of humans that make us different animals? While whites mourn the abolition of slavery and blacks are asserting their freedom how do we explain highly educated Indians voluntarily seeking their own subjugation by supporting the imposition of the Emergency by Indira Gandhi 40 years ago? Siddhartha Shankar Ray was a barrister and grandson of a freedom fighter. Yet he was the main instigator of the Emergency, in complete violation of the constitution. But the violation of the constitution did not end in 1977. Seems that Ms Sonia Gandhi approved of the Emergency. Between 2004 and 2014 Ms Sonia Gandhi ruled India without any accountability by appointing a Prime Minister, not elected by the people, and on the advice of a bunch of leftist imbeciles, who made up the National Advisory Council, also not elected. The Congress will do anything to keep this family in power. Is their something in our genes that makes us so meek that we allowed Muslim invaders to rule us for centuries, followed by the British, and have repeatedly returned all the gains made by the sacrifice of our soldiers against Pakistan? Perhaps races are different even if it seems unpalatable.
