In Denmark, the Facebook group "Boycott goods from the USA" has nearly 40,000 members. There, tips are shared on how to replace everything from Google to ketchup with European variants.
The Swedish protest group has a more modest 5,700 members on Friday.
Tesla sales plummet
Left-wing leader Nooshi Dadgostar believes that boycotts can have a real effect regardless.
It has become a popular movement for consumers to express their discontent, she says, and continues:
Donald Trump seems to have forgotten that Europe is an equal economic power to the USA, so if you make European consumers angry, it will be felt, it will cost the USA.
She takes Tesla cars as an example. Earlier in the week, it was reported that sales of Elon Musk's electric cars are plummeting in Europe.
Avoiding as much as possible
That makes Elon Musk significantly poorer, says Dadgostar.
Will you continue to buy goods from the USA yourself?
I will avoid American products as much as possible after what has happened. I would never buy a Tesla car today, for example.
Elon Musk is a person who has been conducting a labor market conflict for a longer period and does not respect the Swedish collective bargaining model. Moreover, he supports the AFD in Germany and tries to interfere in European democracy.
