Welcome. That's a mighty long time to flog a dead horse. Now that you've discovered that's what you've been doing all that time.
I noticed that same attitude last week with my visiting sister-in-law. Neither of them are JW's, but she works with a few. They're all nice people. Not an issue. But I asked her what they thought about the ARC and how the WTBT$ dealt with child abuse worldwide. Her attitude to me was dismissive & patronising. I registered it but moved on.
I've just erased what I was going to add. But you've captured it in your OP. Ease up on the resentment though and channel your mental energy into living what's left of your life.
