That the idea live and let live, don’t bother others and they won’t bother you, are wrong.
Being peaceful makes you a trouble magnet. Trouble makers don’t look for people who make trouble to annoy. They steer clear of dangerous, volatile, violent people and make a bee line for quiet, courteous people. Violence shows a consistent pattern in violent to non-violent, strong to weak. The violent and obnoxious seek out soft-targets. Victims are disproportionally women, children, the young, the elderly and disabled. But presenting as a civilised person can be interpreted as weakness. People who do not expect to be attacked are easy targets.
It seems we are no longer living in a civilised society, where the rules protect the law-abiding from the lawless. We are being left to fend for ourselves, where we cannot even rely on those institutions which were supposed to protect us. Children are bullied in school while teachers and administration turn a blind eye and assert there is no problem. Elderly and vulnerable disabled are treated callously in hospitals and care homes. The police scorn householders plagued by gangs. But they have the resources to hunt down the homeless and separate them from their last possessions. Bureaucracies make mistakes then punish their victims. Western civilisation seems to be dying to the jeers of those most active in tearing it down.
Perhaps in the absence of the will to keep building and maintaining a civilised society, the laws of nature fill the vacuum. The new rules are, be weak and become a victim. Those who aren’t able, willing and equipped to defend themselves, individually and collectively, will go to the wall. If you don’t hang together, you will hang separately.
Of the citizenry of the Western democracies, the Americans are best placed to protect themselves from the climate of anarchy. The Europeans are defenceless, as many of them have already discovered.
