It comes off much more like a bias rather than a safety precaution. When you begin to categorize people in different ways there becomes a problem of objectivity. It's quite near impossible for people to be objective, personal biases exist and that is a simple fact. There is no way to go through those that are in the complex and judge whether or not they are the right kind of person. The word right carries the connotation that diversity is a negative thing and that someone has the stature to judge others, which I am certain no one would appreciate here. A great many of us are displaced and therefore in the same situation. If you're worried about your safety I suggest taking extra precautions for your own living arrangements. I'm certain that those in charge of security at the complex would be all too happy to help you feel safe, but I'm confident that the complex security is rather accurate. There have been few incidents at the complex since I have arrived.
Beg your pardon, but though I may be from another planet I am perfectly capable of reading. I've acquainted myself and become familiar with everything that I need. I can assure you that I am far from ignorant. My opinions are formed from what I have research and found out combined with what I knew from home, where I might add I was a Queen. Perhaps you should reassess your comment, I know a lot more than you seem to have first assumed.
