1. A psychotic disorder characterized by delusions of persecution with or without grandeur, often strenuously defended with apparent logic and reason.
2. Extreme, irrational distrust of others.” – http://www.thefreedictionary.com/paranoia
“The symptoms of paranoia are diverse, but one of the most common is a strong distrust of other people. Often, paranoid people suspect that those around them are plotting against them and question the motives of others,m leading them to be tense, oversensitive, and confrontational. They are unable to relax around people because of this lack of trust and often are quick to take offense to others’ actions, which may make them uncomfortable at social functions. Other symptoms may include extreme stubbornness, perfectionism, and difficulty in expressing forgiveness, although these may also be signs of other mental disorders.” – http://www.wisegeekhealth.come/what-is-paranoia.htm
How many times does a person have to be burned, stabbed in the back, spat upon, before at least a measure of paranoia evolves? How long before you begin to adopt the X-Files warning to “Trust No One”?
When you read or hear that some certain group of people would like to see you, or your kind, dead or dying, at what point do you circle the wagons, or close the door and lock it securely?
“Not all are like that”, they cry in reassurance. Yet they fail to demonstrate that what is spoken is the truth … their actions betray them.
So you walk with care, like upon pins and needles, saying little, or saying everything with diplomatic care, so as not to ignite a spark.
Nevertheless, at some point the ignition will take place, most likely the moment they suspect you are treating them with diplomatic care, not speaking all, and walking with tender care.
