The Democrats and the business community say that the entry of blue collar workers from Mexico helps the US economy. Silicon Valley has been insistent that Trump's proposed denial of business visas to Indian software engineers will harm the businesses there. But for Trump and his supporters the issue is clear: America needs to be kept pure. Mexicans are rapists and criminals and Indians are taking away the jobs that should rightfully go only to American citizens. Trump refers to nations that are not white as "shit-hole countries". This is the sort of violent rhetoric that when injected into the political debate inspires and produces violence. It is not surprising that if you look at the instance of such things in the West in the recent past, it is members of the 'Right' who have been responsible. An American member of the House of Representatives (their version of our Lok Sabha), Gabrielle Giffords, was shot in the head in 2011, by an individual who identified with the Tea Party, the extreme wing of the Republican Party. In 2016, Jo Cox, a woman in the United Kingdom version of the Lok Sabha, the House of Representatives, was shot and killed by a man who opposed her pro-immigration policies and called her a "traitor to White people." This happened in the lead up to the vote on Brexit, when the most important issue was that of immigration.
