In any case, Trump and Brexit proving to be complete disasters will soon squish the rise of the far-right, as we can already see happening in Europe.
The far right recently lost a presidential election in Austria, they underperformed in the Dutch elections, UKIP suffered a major blow in UK local elections the day before yesterday, and the far right will almost certainly lose tomorrow in France.
The AfD also declined somewhat in opinion polls in Germany, but that's more due to ongoing internal power struggles.
