I think the worst part about Trump are his ideas about climate change. If a big industrialised country like the US doesn't help to stop climate change right now, it may cause millions of deaths by the end of this century.
Trump is very selfish, he tells people what they want to hear, and not what's actually good for humanity and for this planet.
What we see is backlash against the fearmongering. The global warming myth was blown out of proportions, and with time more and more people saw behind the lies. Psychologically this creates a counter-reaction. An increasing amount of people are sick and tired of the fearmongering and the shaming and the playing on guilt, wether it's about global warming, the refugee crisis or the European Union.
You can't expect to shame and bully the Western citizen into taking the whole responsibility for all the world's problems and not get anything back but increased shame and bullying.
How fun do you think it's for a white guy to be blamed for all the problems of the world, constantly be called entitled, a sexist, a misogynist, a racist, a homophobe, a fascist and egoist? And yet he is supposed to pay for climate change, he is supposed to provide for the refugees, he is supposed to be the absorbing airbag when somebody from the outside is frustrated. And on top of it all he gets bullied and beaten up and becomes a minority on his home shores. Never given even one thanks. This equation just doesn't work in the long run. Eventually people will be fed up and react.
Trump is just a catalyst for this counter-reaction. And it will happen time and time again if the left keeps shaming and bullying the members who make up the backbone of our society.
