It appears that US Sikhs are appalled at being clubbed together with Arabs as prospective terrorists:

"That gives the impression some members of the Sikh community are involved in terrorism," said Manjit Singh, president of Sikh Mediawatch and Resource Taskforce (SMART) which works toward accurate representation of Sikhs and Sikhism in American Society and media. "Sikhs are not connected in any way to 9/11."

My comments:

1. Though Mr Manjit Singh may be correct about the non-involvement of Sikhs in 9/11, his statement is not wholly accurate.

2. I know I am again building up negative karma, but this is too good to resist: the acronym of an organisation founded and run by Sardars spells "SMART". Go figure.
