I agree mate about the tone of the language. However, imho, the Attorney General may have played into the hands of Trump and given him a cheap propaganda shot which his supporters will lap up. If Trump's executive order is actually lawful she should have resigned saying that she could not enforce it rather than ordering judges not to enforce it. Thereby giving Trump a reason to have her removed.
I do worry a little about the hysteria (although it is understandable). What is needed is for influential people who oppose him to keep a cool head and to pick their battles more carefully. Simply attacking him seems to entrench his support even more.
As an aside, another consequence of Brexit is that we need the Americans more than ever, hence Theresa May cosying up to Trump. This at a time when their President is so unpredictable and inward looking. It's like we are being forced into a pact with the devil, the effect of which may end up being quite unpalatable.
