You can disagree if you like but they have more support here than in any other part of the country. Here is their largest mosque after 9-11. All the flowers and gifts were given to them because a few people said a few bad things about them as muslims.
Additionally this mosque is one of the largest and oldest in the country and has a special significance as a holy site. They can skip visiting Mecca and go here instead and it's acceptable for their religious requirement.
We're as safe as we can be here from a major terrorist attack. We have about 70,000 muslims in the greater Seattle area alone.
