My OP isn’t meant to be about regular common sense precautions. I’m talking about things like never opening the front door or having a bit of a chat with a new person
We live in a world in which malign media organisations such as News International, or whatever its called now, have huge influence, and inculcating fear is extremely profitable for them.
Think of the thousands of messages, subliminal and not so subliminal, that the average persons receives through print (so-called "news"), broadcast news, sm, and even entertainment in the form of films and TV, or video games, about how hostile the world is generally; endless stories about risks to our health from travelling on holiday, to eating the wrong thing, to climate change, to impending war, to not exercising properly, or not eating enough of something, to dying early bc we befriend the wrong person, or dying early because we do not having enough friends, and that's before we get to actual news reporting on wars, terrorism, criminality, transport disasters, diseases, from all over the world 24/7, plus all the films and tv dramas about kidnapping, rape, hostile aliens and so on.
The agenda is set by men who seem to thrive on, and appear interested in, conflict, hostility and aggression.
Newspaper headlines which plant seeds of fear receive more clicks = more revenue. It's as simple as that. We only hear about the negative side of life and rarely about the wonderful things that happen every day, the miraculous way our bodies function, the beauty of nature as well as its harsh side, the simple acts of love and care that people carry out for one another endlessly and selflessly. Anything that is measured, balanced, not hyperbolic, is rejected as boring or unworthy or not generating enough profit. Women's voices and concerns are shut down. The nurturing and care of others is seen as somehow inferior to "proper" work.
Nowadays we learn about human misery in all its forms from all over the globe, whereas in the past we would only know about things happening in our local village or town and would have had only a vague idea about world events. And increasingly, a young person who lives via the internet, does not get out enough in to the world to enjoy human contact and experience for themselves the fact that in reality the majority of people are pretty ok and it's just a few who ruin it for the rest. They just don't have the first hand experience that contradicts and counter balances all of the scare stories. The reality that life for us in the west at least is pretty mundane and reasonably comfortable as compared with life in some precarious, violent, third world countries where there is little to no free speech or established judiciary, or modern medicine, but it's hard to compute and understand that when the majority of messages we receive about the world on a daily basis are so thoroughly negative.
