There’s bound to be dozens of people who agree with them.
We have a test case here that suggests that there aren't dozens. There are maybe a handful of people at most.
There's one person who will insert themselves into every thread to argue that Domino's is the devil, despite loudly not having consumed their pizza in years and refusing to actually even look at their pizzas to be an informed critic, and who attempt to derail every thread into these arguments.
There's about two people who will never admit that Domino's makes a mistake, including one who will invent truly silly arguments to justify anything that happens -- that person whom a Domino's driver ran over actually
intentionally threw themselves in front of the car in an attempt to manipulate the stock market -- and another person who seems to view anyone who mentions that Domino's got their order wrong as someone to be stalked and harassed until they finally choke on pizza crust.
No one is better off having these people on their threads, since they aren't discussing pizza in good faith and one of them is almost certainly trolling everyone.
Now, we also have at least one person who loudly proclaims how much they hate posters like the first one, but seems to spend about half of his time here responding to them. So I'd argue, for that person and people like them, engaging with trolls is their primary reason for visiting pizza discussion forums, whether they admit it (even to themselves) or not.
But for everyone else, mash that ignore link and move on. This is a quality of life decision that you're in charge of and being mad at people who, for whatever reason, intend to spend all of their time posting AI-level responses on every pizza forum, is a self-inflicted headache.
