...trying to assure insecure people that you have nothing to fear from people that look/sound a little different than you.
Its the inhumane slaughter and torture in their homelands, the unbridled slavery of women and minorities, the culture and ideals from whence they come... and carry over with them, of which our people have died at the hands of, that concerns us. A person does not erase their mind when they cross a border. They remain who they were, a culture that is dynamically opposed to the very existence of western civilization and the rights for which we stand.
By default we are very open and accepting, but when our people start dying it becomes another matter. One that must be addressed. Trudeau believes this too, he is there for the same reason. Paltry though it may be in the face of communications and cultural crossover from the Middle East carried in by fresh refugees or over the internet. Think a drive-by visit and some kind words has more influence than a lifetime of identifying with and adopting culture from their homelands via close associates or instant communications?
Today's world is not like previous generations. There's hardly any separation at all by crossing the globe. Immigrants are not isolated in a strange new land where it's an effort to survive. Where in that struggle new bonds of kinship and brotherhood are formed. They need not form new bonds at all with their fellow Americans (Canadians alike). Isolation can be harbored, hatreds festered, and the disease of Islamic terrorism spread throughout our land without us even knowing it. It is a problem people carry with them, and there's a very distinct and specific group who are susceptible.
Assimilation, the function of an American melting pot, should be our chief response here. Some words to start, sure, but it takes a FAR greater and deeper commitment to achieve peace in a world this dangerous. Those who identify with the Middle East need cultural icons to draw inspiration from. They need leaders committed to our western rights as much as we are. Fostering such people (in our homelands) will require lifetimes of effort, over generations. They will need money and influence over their peers, to stand above and lead them away from the horrors of their homeland. When their people find peace of mind, so too will we who live with them.
