What else?

Some Canadians are imposing a travel ban of their own — boycotting the United States after Donald Trump issued an executive order that forbids visitors from seven Muslim-majority countries from entering America.

“Officially decided not to go to a conference in the US this summer. Might not step foot on US soil until 2021,” Emmett Macfarlane tweeted.

Macfarlane, an assistant professor of political science at the University of Waterloo, told Yahoo Canada News that he was stirred into action after Trump’s executive order was announced on Friday. It bars citizens from Iran, Iraq, Libya, Somalia, Sudan, Syria and Yemen for 90 days, as well as suspends admission of refugees for 120 days.

“It doesn’t feel right to attend a conference that other people may simply be prohibited from on the basis of their nationality,” he said.

Macfarlane recently did postdoctoral research at Harvard University and he and his family have visited the U.S. many times in recent years, including trips to New York, Alaska and Oregon. But he won’t be travelling there in the near future.
