As a science teacher, I had an activity where I gave students a jumbled list of inventions and dates – and I swiftly found few students had any idea of the progression of human discoveries. Although they were young, they did not know of a pre-internet time nor could they comprehend what it was like. As for black-and-white TV, this was almost inconceivable, even though soon television itself may soon be a forgotten memory, along with newspapers.

History teachers should be starting their own revolution, rather than telling of previous ones and breaking the internet to establish what happened, when and where, and what the consequences were then and now.

“Those who cannot remember the past are condemned to repeat it.” It is difficult to see what will happen with fake news stories and now stupid news stories and how they will be remembered in the future.

Learn what happened and tell the truth always. It shouldn’t be that hard to do.

History shows liberals have polarised the US

Democratic Party progressives instruct Americans that pale male croupiers load the dice and stack the deck to rig the country’s elections. In other words, the race starts at the finish line for the favoured. And, while Donald Trump is one of the favoured, he behaves like a no-nonsense, unapologetic philistine, while Joe Biden apologises like an Obama doppelgänger, seeking credit from progressive legions.

However, he does have a long history of understanding what progressives fail to note, namely that they have bitterly polarised our republic by careering far left.
