From the sound of that, I can only assume you are the product of a New York style multicultural white male bashing education. Actually, though new to South Carolina, I found it a rather refreshing change from the PC lunacy of the big city and most of Europe. And folks here are proud to show the American flag, including transplants.
But in answer to your question, it's not Indian attacks we ward off here, but idiot attacks. And for that we use computers quite handily.
How do you know when you're staying in a South Carolina hotel?
When you call the front desk and say "I've gotta leak in my sink"...
...and the person at the front desk says "go ahead".
Every once in a while some a-hole goes into a bar some place looking to get his ass kicked so he starts insulting strangers and acting like a prissy little thing and every once in a while some a-hole jumps anonymously on a computer and does the same thing. Difference? You gotta have at least some respect for the a-hole in the bar. The a-hole playing with his keyboard is like a 10 year old ringing a doorbell then hiding in the bushes.
