If all of Britain is indeed "up in arms" over Trump's retweet, then Theresa May is merely reflecting the concerns of her fellow Britons. She may be an idiot, but she appears to be the idiot the British want and deserve.
True, true!
They can’t be up in arms because the government confiscated them all.
I disagree that PM Theresa May represents the will of the citizens of the U.K. The U.K. Prime Minister of is not directly elected by the citizens of the U.K. First the Prime Minister has to be elected as a Member of Parliament in the House of Commons (stinky peasants) by their local constituency (like a congressman in the U.S. House of Representatives). After that the House of Commons elects from their own a candidate to present to Her Royal Majesty the Queen for Appointment. Many of the Prime Minister's executive and legislative powers are actually royal prerogatives which are still formally vested in the Sovereign, who remains the head of state. Legally the Sovereign can sack the Prime Minister at any time.
Therefor Theresa May represents more the choice of royalty, the aristocracy, and the ultra-rich rather than the people - just like the U.S Senate Majority Leader.
The assault on facts, free speech, and the freedom of the Internet is driven by fear, not confidence. The global establishment's dam is leaking and when it is breached, there will be a lot of members from the “Old Families” either dead or in prison.
