There was a programme on the radio (BBC Radio 4) called "Start the Week" just now. Among the many items it noted how bad colonialism was for the indigenous people. Time and again we are fed a filtered version of events - basically what governments want us to hear. This is especially true in wartime, but it happens all the time, although we do not realise it. During the Vietnam War we were brainwashed to think communism was always evil.
I make no judgements but urge us all to beware of propaganda. Both sides in the BREXIT debate were guilty. There is a general uneasiness in the general public with the people we put in power. This is true in the UK, USA and in many nations in Europe. The lurch to the right in recent times is, in part, a reaction to this. The people who govern us must be unbiased, fair and honourable people if they are to properly represent us. Sadly, I can think of not one politician that I think meets these high standards anywhere in the world.
