Do not panic. While this may be a hostile and dangerous situations, if you are properly prepared, and righteous, you will prevail. Avoid eye contact at all costs - they perceive eye contact as a direct challenge to their social stature. In fact, try to stay as far away from them as you can. If it's not already located as such, move your bed and that of any of your loved ones to the far side of the apartment from where they live. Try not to place yourself in any situation where you may possibly have to breathe the same air as they do.
Terrorism is contagious. I'm sure you can still find some face masks from the sars scare a while back. Here's a
link if you can't find any. Invest in about three years worth. That might not seem enough now, but remember, A-rabs typically live short lives in the U.S., as they have the overwhelming desire to strap explosives onto their bodies and detonate them in the hopes of harming a God-fearing U.S. American.
If you must interact with them at all, go for their hands, first. If you hesitate, and do not attack first, they will murder you and your loved ones in the most despicable of manners - and likely on camera, to further intimidate their Christian enemies. However, the odds aren't at all against you: A-rabians are typically not the fastest of hand-to-hand combatants, as they haven't been blessed by the good Lord and Dubya both, so you still have a fighting chance. Just break, cut off, or otherwise dismantle their ability to use their hands at all. This way, they cannot rub on their magic lambs, and summon djinn.
After removing their use of their hands, immediately call 911 and request to speak with Homeland Security. They will be able to give you more precise instructions for what you need to do next. It may get ugly, but remember: it's your duty as a U.S. American to do the right thing, and safeguard our rights as a free-thinking, Christian society.
We salute you, and will keep you in our prayers.
