The ever-expanding definition of "tolerance" [LINK]
From the website of Hot Springs Bed, Breakfast & Books, "an open minded tolerant [read: gay-friendly] house perfect for couples or those on their own exploring Hot Springs National Park" in Arkansas:
Hot Springs National Park... A rich history of peace and tolerance dating back to indigenous times. Hot Springs, known as "The Valley of Peace" to native Americans was a neutral zone where even tribes at war could send their elders and sick to restore their health in the local spring waters. Hot Springs' mission of tolerance continued through the 1960's with tolerated gambling, vice and as a neutral zone for the mob.
