It's been a while since I participated in a political debate on one of the TI commmunity's message boards. The first time was in 2002, for the French presidential election, where an extreme right candidate got into the second round because the French extreme left said "oh, left wing is not left-leaning enough, we are the true left wing". Too many people voted for these crooks and evicted the left-wing candidate from the second round, and caused eveybody to withstand 10 years of right-wing, economically liberal government after that.
But anyway. The stakes are much higher here (USA, 2016) than France, 2002.
First of all... you know, a number of countries use (far) more "socialist" views than the USA does, and they're doing pretty well, both economically and humanly
Much less inequality and poverty, better education for the masses, longer life expectancy (despite Obamacare, the USA remains a complete outlier on a graph displaying life expectancy as a function of time and average cost, with average expectancy still about 5 years lower than the best countries and health care about twice as expensive as the second most expensive country - sadly I can't find the link to that eye-opening graph quickly right now, but yes, it's based on serious publicly available data...), etc. That's because the powerful machine for transferring trillions of dollars of money from the poor to the rich, namely economical liberalism, was implemented less, and has therefore less damaged other countries.
Where I live, Democrats would be far right because of their ultra-liberal views, and Republicans definitely extreme right, due to racism / xenophobia, in addition to even worse ultra-liberalism.
If one's aiming for self-destruction of the Western world and probably most of the world, then voting for an unstable proto-fascist, serial populist liar (I saw a bar chart indicating that Trump was, by far, the most "pants on fire" and least "completely true" candidate among dozens when going through fact checking, while Obama and Clinton were the two least dishonest candidates with the most "completely true" and the least "pants on fire"), serial public insulter (a respected newspaper recently made a full two-page list of his recent insults !), proud serial sexual assaulter (...), pro-nuke usage, and lots of other nastiness and craziness, is part of the way to go.
Brexit, voted mainly by old dumb and misled (the amount and magnitude of lies told to them was staggering, just like in the US presidential election) people in rural areas (who won't suffer the consequences of their own silliness for more than, say, 10-20 years, and won't switch countries), while young educated urban people (who will suffer the consequences of other people's silliness for 40-60 years, and for whom leaving the predictably destroyed country is easier) mostly voted "Remain" - with good reason - was another milestone on the Western world destruction path, too, pretty much due to the same loathsome tactics by the "Leave" camp. The rest of the world told them that they were screwing up big time, too.
I'll leave that as a closing note:
