It is up to you what you find convincing or acceptable, but as a strategy I don’t like yours - Facebook can come (and does) come up with bad faith arguments. If you keep responding to them, they waste your energy evaluating and responding to each argument. They have unlimited resources, in comparison.

The only reasonable way, in the long term, is to ignore the specifics and address the essence. Some of us have been observing this behavior (with many companies and politicians) for decades, and choose bot to play the game dictated by the other side.
