Whilst Trump is a bit of a phenomenon, the USA is less far right now than it was 50 or 60 years ago, when white men were literally the ruling class. Compared to post ww2 it’s quite liberal.
I think extremist and their views have always existed, in the USA,Europe and the UK. The age of the internet has just made them more visible, and enabled them to organise themselves into groups or political parties.
The solution is those that sit anywhere left of the far right need to present better arguments to counter them, wasting money flying a baby balloon won’t have present a very educated alternative for those sitting on the fence of being either for or against Trump.
