Jaisreer,
I think you are mixing a number of issues into one. I know that some people are using Islam's name to create terrorism in the world. But it is extremely wrong to target each and every muslim person in the world.
Nobody is asking them to stop frisking or checking people coming into their country. They have full right to choose who they want to give Visa to and who they think should not come in their country.
But once you have given the Visa to a person, they should try to trust their own people and not treat passengers like criminals on US airport. Shahrukh didn't go their hiding in a trunk. He went their with visa and complete papers. So, did President Abdul Kalam....
