Firstly, there is still a mystery as to what exactly happened in Godhra, and who was responsible for the killings. Secondly, the particular persons who were responsible for the Godhra killings should certainly be identified and given harsh punishment, but how does this justify the attack on the entire Muslim community in Gujarat.
Muslims are only 9% of the total population of Gujarat, the rest being mostly Hindus. In 2002 Muslims were massacred, their homes burnt, and other horrible crimes committed on them.
To call the killings of Muslims in 2002 as a spontaneous reaction reminds one of Kristallnacht (see online) in Germany in November 1938, when the entire Jewish community in Germany was attacked, many killed, their synagogues burnt, shops vandalized, etc after a German diplomat in Paris was shot by a Jewish youth whose family had been persecuted by the Nazis.
