I think that Trump is a typical case of "either you like him or hate him". There doesn't seem to be any middle ground
People say that "either or thing", I don't hate them for it but it's a bit annoying.
Polarising is a good word, they could refer to bell curves and deviations, distributions.
I expect there is a middle ground.
I find him repugnant but I don't hate him.
He hasn't fondled anyone important to me.
