A preview of the sticker was posted on Gazeta Polska’s Twitter feed on Wednesday and it is due to be included in next week’s edition. US ambassador to Poland Georgette Mosbacher expressed concern.

“I am disappointed and concerned that some groups use stickers to promote hatred and intolerance. We respect freedom of speech, but we must stand together on the side of values such as diversity and tolerance,” Ms Mosbacher tweeted. In response, the newspaper’s editor, Tomasz Sakiewicz, tweeted that “being an activist in the gay movement does not make anyone more tolerant”.
