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.
They implement such systems precisely to always be in charge.
