You are either stupid or blind.
Muslims have no intentions of integrating with other Muslims, let alone integrating with Christians, Jews, Hindus, Atheists, etc. The truth is many want to kill people who don't follow their strict regime of beliefs.
This started the moment they buried Mohammed. They couldn't decide on his successor, split and started killing each other.
They're now in the West insisting we adapt to their beliefs and the liberals telling everyone we should. To make them welcome. This is bullshit.
Many will not stop until we entirely bend to their ways. They couldn't even respect the dead of 9/11 insisting they have an Islamic Center close to Ground Zero. The argument over it was about their rights and not those of the orphans, widows and widowers left behind. The constant insistence that terrorists killing people in the name on Islam aren't real Muslims, is more bullshit.

Fears over deepening Sunni-Shia divide in UK - BBC News
Muslims are leaving the West to go back to the ME, to kill other Muslims. They would be doing this with or without any involvement from the West. The Shia- Sunni divide has been with them from before Mohammed. Islam just gave the divided tribes another reason to kill each other.
Why should we give them anything when they refuse to give to others?
