In an article about Symbols of the Gay Movement there's a paragraph about the Gay Jews in the Nazi concentration camps who were forced to sew pink Stars of David on their clothes.
My impression is that this piece of information is so repressed that when you search the keywords "pink Star of David" on Google images you get about 300 results most of them are gift items and not even one result that matches the intention behind this query. I believe the creators of these gifts weren't acquainted to the historic meaning of their labels; maybe if they knew they would have made their gifts in other colors or changed the labels of their products.
Elizabeth Olson wrote in the New York Times on January 4, 2003 about The United States Holocaust Memorial Museum decision to focus exhibitions on other groups beside the Jews, beginning with homosexuals. These other groups include handicapped, Gypsies, Poles, Soviet prisoners of war and Jehovah’s Witnesses. This first exhibition was entitled "Nazi Persecution of Homosexuals, 1933-1945".
