It also doesn't seem unreasonable to, for instance, check on someone's social networking or other history when they are applying to enter the country.
I'll add checking their Facebook and Twitter accounts to the screening process.
@Spoletta - Islamic terrorism and creeping Sharia pose a real threat to Western lives, society and culture.
The only point I can agree on is the tragic loss of life. But the majority of lives lost to terrorism occur within the Islamic countries themselves. the lives lost to terrorism within the Western nations are tragedies, but numerically insignificant when compared with other more preventable losses of life.
As far as society and culture are concerned, I find it very unlikely that we'll be bowing to Mecca and wearing hijabs in the future. Every culture that has come to America has only added to the diversity of our nation, while eventually assimilating into the general populace. There will always be small enclaves of every culture somewhere that we can visit to discover a more ethnic experience. But I've yet to see any of these expand and engulf an entire region.
Your flippant attitude REALLY DOESN'T HELP!
When thoughtful discussion fails, I find a little sarcasm goes a long way when I want to point out fallacies or weakness in another's arguments. It at least makes me feel better.
