The Polish artist Daniel Rycharski sat in his childhood home recently and considered the idea of fitting in. In many ways, Poland is a highly polarized country. On one side is the right-wing populist government of the Law and Justice party, with its many rural supporters, which purports to stand for “family values” and the traditions of the Roman Catholic Church; on the other is a more liberal opposition, which finds most of its backers in the country’s cosmopolitan cities. Mr. Rycharski said he had no intention of changing his approach, whatever problems it caused him. “If I can change Kurowko, Poland can change,” he said.
