Attorney and former Harvard Law professor Alan Dershowitz says a vendor at the West Tisbury Farmers Market on Martha’s Vineyard refused to sell him pierogi because of his political positions and past representation of clients such as former President Donald Trump and the late financier Jeffrey Epstein. Dershowitz contends the denial violates Massachusetts public-accommodations law, which bars discrimination in retail transactions. The 85-year-old lawyer has threatened to sue the market unless it requires all vendors to serve every customer. He later told the Boston Globe he would be “satisfied” if the market adopted a non-discrimination policy and enforced it. Separately, a Florida pierogi maker has offered Dershowitz free dumplings for life, turning the dispute into a broader culture-war flashpoint.
