Trump wants to disrupt global trade so people making their own small disruption is an odd way to protest that, although I understand the sentiment. Shipyard Brewery are not my enemy and I hope I will continue to be able to buy their beer in the UK.
When one person makes such a disruption, it is small. When entire countries are actively suppressing or removing U.S.-made products from the marketplace, the effects are of course much stronger, which is why I gave those links as only just a few examples.
