They can’t maintain their beliefs about 1919 without retaining 1914 so they’re a bit stuck. It really is pathetic.
But they likely rarely mention it, and they are much less likely to mention October 1914 because the war has already started and something was supposed to happen suddenly in or after October (and Russell didn’t say anything at all about ‘Satan being thrown to earth’ because he believed the ‘dragon’ referred to pagan nations.)
Apart from the vague notion about the ‘end of the gentle times’ (an Adventist teaching), nothing that Jehovah’s Witnesses now believe about 1914 was taught by C T Russell or even when they were supposedly ‘selected’ in 1919.
