Violence amongst the Sikhs versus amongst the Muslims
In any other political climate, a U.S. president's visit to a historic Sikh temple and major Indian tourist attraction would be about as noncontroversial as a foreign state visit could get. The Sikhs, after all, practice a studiously inclusive, noncontroversial faith that shuns violent conflict of all kind.
- White House cancels Obama trip to Sikh temple over Muslim rumor concerns
I suppose that it was nonviolence that downed that Air India flight, or assasinated an Indian prime minister (because of an event that involved that same Sikh temple that Obama was to visit). Or, in Surrey, BC:
Watts said she was disappointed the parade included a float honouring Sikh separatist extremists as martyrs. ...There were also posters of men who founded what are considered terrorist groups and who played a role in assassinating Indian prime minister Indira Gandhi, along with the slogan "They gave their today for our tomorrow." ... This is not the first year the parade has drawn controversy because of its support for Sikh militants in India.
That there are some Muslim terrorists does not imply that all Muslims are terrorists. Similarly, even if most Sikhs are peaceful that does not imply that there are no violent Sikh organizations.
