It might make more sense to focus on supporting companies that do something right, since at this point the shareholders and employees of all companies are different than what they were a century ago. Should be boycott British (including Canadian and Australian and the United States) goods over the expulsion from England in 1290, or boycott Spain and its former colonies of 1492.
Should we boycott southern states over the Leo Frank lynching (which, BTW, is a major reason why secular Jews with American roots predating the World Wars tend to perceive the American south as inherently hostile to Jews)? Should we boycott Ford since the company’s owner pre-World War II was openly anti-Jewish, or forget about that since post-World War II Ford was a leading company in refusing to boycott Israel? What about General Motors (which technically is only about 10 year old since the original GM went under and the new company owns the name but is not the same corporation)? Should we prefer Leica’s very excellent but overpriced cameras since the owners of the company during the 1930s “outplaced” their Jewish employees into jobs in the industry in places outside of Germany? Should we boycott all the countries that refused asylum to Jewish refugees during the holocaust (which included the United States and the British Empire)?
While it is good to know the past, it is counter0productive to live in the past.
