You can't have the Holocaust (with a capital H) without the Jews being involved.

Yes you can (any capitalization is irrelevant... we are talking about the general term here of both lynching and holocaust). Holocaust is simply a Greek word meaning completely burnt. Any mass genocide can be called a holocaust.

Since the mid-19th century, the word has been used by many authors to refer to large catastrophes and massacres, particularly those caused by immolation. According to the OED, the earliest attested such usage dates from 1671, but it became common in the 19th century. In 1833 the journalist Leitch Ritchie, writing about the medieval French monarch Louis VII, wrote that he "once made a holocaust of thirteen hundred persons in a church". This refers to his invasion of Vitry-le-François in 1142 during which the 1,300 inhabitants of the town were burnt alive in the church.

By the early twentieth century the term was widely used to refer to massacres of Armenians in Turkey, particularly during World War I. The Armenian Genocide was called "The Holocaust" (1920) and "The Smyrna Holocaust" (1923).^[2] In 1929, Winston Churchill referred to "helpless Armenians, men, women, and children together, whole districts blotted out in one administrative holocaust" (The World Crisis).^[3]
Even before the Second World War, the possibility of another war was referred to as "another holocaust" (that is, a repeat of the First World War). With reference to the events of the war, writers in English after it was over tended to use the term in relation to events such as the fire-bombing of Dresden or Hiroshima, rather than the Nazi genocide.^{[citation needed]} The term was most commonly used to refer to the destructive consequences of nuclear war.^[4]

The term became increasingly widespread as a synonym for "genocide" in the last decades of the 20th century to refer to mass murders in the form "X holocaust" (e.g. "Rwandan holocaust"). Examples are Rwanda, the Ukraine under Stalin, and the actions of the Khmer Rouge in Cambodia.
