It is one of the most irritating and bad faith tactics they use. I always try to highlight this and then rein them in a bit, making them pick one at a time to go into in more detail in a good faith way, and that we can pick through them one by one but doing it all at once is unfeasible. 99% of the time they immediately disengage because they're not interested in a good faith discussion.

The best and only outcome I think that is possible when this happens is trying to highlight to other readers that the user of this tactic is not acting in good faith and is not interested in truth.
