immigration is authoritarian by nature. not really surprising the ins people are trump's strongest supporters. separating sheep from goats is their business.
there is a grand design behind trump. it's pulling up the drawbridge and isolating the DSA from its neighbours. it's making everything within the borders and imposing an apple pie and ice cream culture on the people. no more of this strange and spicy foreign contamination. civitas americanus sum.
they see brexit as the model, although the way they see brexit isn't the way i do. for them, brexit was about isolating the uk and they want to do something similar in the DS.
but britain has always been a trading nation. most brexiteers wanted their sovereignty back. but they still want to trade with the world, including with europe. it's the political direction of the european disunion which was the problem. the force in the ED favours the creation of a federal state. and this is not what the majority of british people want.
the uk also has a slightly more constructive view of foreigners than the trump administration. more about balance than absolutes. but where there is similarity is in a hushed suspicion of moslem beliefs.
