I'm going to reitterate my offer - I have a guest bedroom available just outside of Washington, DC. There are a lot of people in this thread that seem to need some first hand exposure to the USA. You're all invited to make use of my guest bedroom. Then, we can go out and dodge bullets as we see the sights. It's basically like a real-life video game here.
This is a really bad argument.
1. Using this kind of argument you could say that pretty much every country in the world is safe, as long as the part where you live is.
Example A: "the threat of terror in Afghanistan is way overblown. Let me invite you to my home in Afghanistan and I'll show you what the country actually is like"
Example B: "I have a nice house with a small guest house in the backyard, come and stay for a week or two and we'll explore Mexico. Perhaps go on a cartel hunt or something."
Example C: "why don't you come visit me in Sweden and stay in my apartment in Stockholm. Show you our country. Get some photos of rampaging islamists, perhaps catch some women wearing burkas."
2. Using the same kind of argument you could argue that your country is the worst place on earth, just switch the location to one of the least secure ones in your nation and there you go.
Example: "Please come and live with me in my house in Detroit. I'll give you first hand exposure of the USA. Bring a bulletproof vest. No seriously, bring a bulletproof vest, it's fucking horrible here."
In short: do not use the place where you live as some kind of measurement for what the entire nation is like, because doing so is not particularly clever.
