not really. its about the differences between muslim culture and western culture.
if you went to a muslim country, you would respect their "culture", which has a religious base. therefore, if you had to take your shoes off to enter certain buildings, then in all likeliness you would take your shoes off, as opposed to suing them for descrimination.
the western culture has a base in religion, but is also upon other customs which have become the norm in our society. handshakes, business dress, etc have all become part of our culture, and are arguably as important to us, as the culture which has become common in other countries.
so what is it about these muslims who believe that their culture is more important, or righteous than ours? they have chosen to uproot and move into another culture, and yet are not willing to make their sacrifices in order to fit in and allow our country to move forward. reducing the features which made it attractive for them to move here in the first place.
