Earth, These Muslim families are living in a culture that is all about freedom of choice, and if they hold an irrational fear ignorance or racism that prevents them from accepting that it is socially correct to be friendly and polite, then they need to address these irrational fears. And this is not racism, get it right, this is not a race, it is a religious belief.
Your points about nuns, your brother's t-shirt and whatever is irrevelvant and has nothing to do with the security risk and fitting in with society. Both these groups fit in. The nuns contribute and support our society rather than the topic at hand which is a religious group who is creating fear and hatred through rioting and scaring our children.It is fine to get all self-righteous about this but you need to get real about what you are saying. We are in a war, and this religion has in Fact been caught supporting a terrorist act. We have every right to protect our country, and it has nothing to do with your brothers t-shirt or a man's speedo.
That is exactly what this is about!! And by creating a new set of social standards that speaks of intolerance, ignorance, prejudice, and irrational fear --to use your words, is not what our country, or the western world is all about.
