The claims track high-end historical estimates for the 1917–1933 period but need caveats. Revolutions/attempts: roughly 8–12 major cases (Russia, Finland, Germany/Bavaria, Hungary, Mongolia, short-lived soviets elsewhere) is accurate; 11 is a reasonable upper count. Churches: ~20–25k Orthodox closed or destroyed by the mid-1930s matches archival and secondary tallies of the early anti-religious campaigns. Clergy: 10k killed is a low-to-mid figure for the full interval (higher estimates reach tens of thousands by the late 1930s, concentrated later); early years (to 1926) show far fewer documented cases. Deaths: 15–25 million sits at the upper range of excess-mortality and democide estimates that include civil-war terror, the 1921–22 famine, dekulakization, and the 1932–33 famine/Holodomor. The large majority were in Orthodox-majority regions of the former Russian Empire.
