One could argue that they may very well think that this sort of thing could never happen, that the center will always prevail etc... but then again I remember seeing this video compilation of a lot of very confident people in the US saying that Trump would never be president a few months before the 2016 election, let alone be elected for a second term.
So that makes me think, how can they so confident that "the good guys" will always be in charge?
Because from where I am standing there is a massive chance that Reform will win in the UK and that the National Rally will win in France in 2027.
Nobody can say that they did not know.
