she clarified that "they" would be coming to round up all JWs and put them in concentration camps just like in WWII. I think she meant the UN
Did she happen to explain how she knows this?
With their atrocious record of setting dates in the past you can be sure that they have no idea. There is nothing in the bible to back up this claim of putting JWs into concentration camps so get her to be specific about where this information is coming from.
