I agree with Minty. It is State visiting State - the personalities are irrelevant. The Queen received Idi Amin, if I remember rightly (and I'm sure I do). People may, and do, object, but ultimately it is in the interests of all residents in these isles to have him on our side - not saying this is straightforward or a 'yeaah, let's be friends' attitude. So, I'm afraid that I say - yes, protest noted and quite understood, but visit must go ahead pleasantly. Trump is thin-skinned. Boris has done well with getting exemptions from travel ban for UK citizens, UK citizens must be our priority i.m.o..
