Why is Trump opposed and treated by many people in mainstream western countries?

Because of the word limit, the brief introduction of the question is written in the answer. There are several common mistakes in Trump's report. Let me explain here. First of all, the leader with the strongest attitude towards refugees and immigrants in mainstream western countries is not Trump, but the seemingly gentle British female Prime Minister May. The main reason for Britain's withdrawal from the EU is not refugees, but legal immigrants. Due to EU regulations, nationals from poor countries in Eastern Europe have almost equal opportunities to compete with the British for jobs in Britain. Poles are naturally willing to go to Britain to earn money and return to China for consumption; The rich in Britain have cheaper labor and are willing to. However, the middle and lower class poor in Britain are not reconciled, and competition has seriously affected their income and life. Of course, this situation is common in the European Union, but it is especially serious because Britain speaks English and there is no language barrier. The British don't want to be equal to people in poor countries in eastern Europe, so they left the EU. What Prime Minister Mei insists on is nothing more than reducing the living space of legal immigrants before. Let them work for British citizens. At the same time, Britain has also confirmed that it will leave the European Court of Justice, which means that Britain will leave the European Union's human rights checks and balances and have greater freedom on the refugee issue. So obviously, Mei's policy is tougher than Trump's. At the same time, the wall used by Britain to stop refugees has been built in Calais, France. Then there is the most crucial point: why build a wall to stop refugees? Violence against women and children is justified because of the separation wall. When refugees or illegal immigrants attack the border, they are often not young people who make up the absolute majority of the population, but women and children. Faced with these women and children, the police guarding the border have no good way. After all, the reporter's lens may be behind this group of refugees. Attacking the border is an act of escape, but attacking the "wall" is a destructive act that can be stopped. Beggars come into your yard to beg. You can't fight Beggars can fight for your wall. This is the principle. These reasons are not discussed in depth by the general media, because the controversy is actually very big, which is different from the impression of ordinary people. However, you should know when writing relevant reports.
