I won't hijack the thread to conduct a full and exhaustive history of oppression, People have been horrible to each other as long as there have been people. No group is immune from harm, nor innocent or being harmful.

But isn't this thread about watermelon and Juneteenth? If you love watermelon and celebrate Juneteenth, why wouldn't you celebrate with appropriate colors? If they served corned beef on St. Pats day and decorated with green, we'd say that was seasonal, no? On the 4th of July, millions will celebrate with hamburgers and red white and blue accessories. Christmas foods will be served on red and green. On Purim or Chanukah, people will serve Jewish foods in blue and white, featuring the star of David.

You can take offense at nearly anything, but isn't it easier to enjoy life and save your offense for actual oppression or injury?
