The people we should be genuinely scared of today are the ones that are looking at Britain's past and are thinking to themselves that colonization sure looks like a good idea that will work super well in modern times. Which not many actual Brits think.
I mean ... Sure but England has got to stop blaming other countries for their problems too. I mean look at the shitshow that was brexit in which the UK claimed the 20 or so other countries of the EU were at fault for their own issues.
Of course with Brexit bare in mind that the majority of the populace did not vote for it. Many of us are very pro-EU and believe in European social democracy.
