Mandela effect it is not. That is just absolute looney tunes.
But i can see that this could seem like something that was"missed". the issue is that they didn't change much. they are still the FDS in 1919. You still have to follow the slave. So in that sense, nothing has changed. That also means that in terms of authority, nothing has really changed. What has changed is the "appointment over the domestics".
I suppose my follow up question would be, does 1919 now hold ZERO significance for JW's?
