I thought it might be useful to start up a new thread for this issue, because it has a lot of implications here (and elsewhere) and I thought it would get lost in the Trump administration thread.
Ms Fadwa Aloui, a Canadian citizen born in Fèz, Morocco, her cousin and her two children were headed in her car to a shopping trip in Burlington (Vermont, I assume?) and they were interrogated for a long time at the US border. She was asked about the mosque she attended, her imam and what she thought of Trump!
This had happened to her before shortly after the WTC attack in 2011, but finally the customs and immigration agents let her through then. This time, they were all refused, despite valid Canadian passports.
And I thought the Church of Shopping was the national religion in Trumpland!
