LOL. I remember spending untold hours on some thread with over 10,000 posts, simply presenting the Catholic teaching on Mary as Mother of God. The same five or six posters would simply ignore the posts and come back with such inane things as “You Catholics believe that Mary preexisted the Trinity”, or some similar nonsense. They were simply repeating the same silly accusations that were already refuted several thousand times over in hundreds of posts over the last ten years.
At that point, I had enough.
I do know what you mean.
It can be exhausting and maddening and saddening.
As I said, that is why I carefully choose to whom and to what I respond.
