There may be violence and insecurity in Haiti, but they are not a threat to us. On the other side I perfectly know that as much as 90% of Muslims would be willing to take over Europe, America and Israel. I have read many Islamic sites and even saw them in chat rooms, and most of them view Europe as a future Islamic state.
I used to be tolerant to individual Muslims in the past, I thought fundamentalism was only encouraged by political leaders for their own agenda... until I got a PC at home and I could monitor many chats and sites all the time (Instead of just an hour in a cyber cafe) and I found out that most of them, even if not interested in pilitics, wish to destroy European democracies and replace it with Sharia. Europe has undergone milenia of dark ages, Inquisition, witch hunt, progroms from inside, and now that we have made a relatively freer society, I certainly don't want foreign Muslims to throw all our efforts away.
