It is imperative when you enter a thread of discussion that you read through all the comments thoroughly. I have seen that FJ has a habit of jumping into the thread without doing her homework on the discussion. Hence, she misses comments and goes totally off the rails. It is like she is wearing blinkers and cannot see beyond her own prejudicial bias.
One skilled in conversationdiscussion/debate can always stay on track despite it being derailed by others.
I empathize with you having to continually and unnecessarily repeat yourself PFH. It is frustrating for those who really want to contribute to the thread.
