James Clapper, former director of National Intelligence made me smile when he questioned Trump's fitness for office saying his "behaviour and divisiveness and complete intellectual, moral and ethical void" was disturbing.
I couldn't have put it better myself.
However, it doesn't mean we don't do business with the USA. I imagine many of the heads of industry and business in the USA agree with Clapper, but they'll still be at the helm in terms of trade and negotiations and won't want to miss out on lucrative deals just because they have a strange President in the White House.
We won't be going through Trump to do deals, and I suspect the intellect of the person starting the petition may be slightly suspect too. The petition is an obvious and rather pathetic attempt at scaremongering and to take a swipe at Theresa May.
