The smearers are so desperate lol. First he's a pacifist who loves all Muslims. Then he's in cahoots with Assad and others who massacre Muslim civilians.
Same as his immigration policy, first he's a hard core brexiter who hates the EU, next he's wanting to flood the country with unlimited immigrants. All part of billionaire-class' efforts to discredit him. Unfortunately for them such extreme and unreasonable propaganda against him has backfired as seen at the last election:
