Many other = 5 million other victims including gays, gypsies, mentally handicapped etc.

The Nazis managed to wipe out ⅔ European Jews and ½ of Roma. These are the statistics that I think highlight the scale a bit more appropriately than raw numbers, because millions is really inconceivable. Gays made up less than a percent of those victims, so less of an emphasis there makes sense, but the devastation to the Roma community is criminally under discussed.
