I think that part of their job is resolving violent or potentially violent conflict.
It’s true that perhaps my situation as described to the dispatcher might not have met a certain threshold, however, it would’ve made sense for them to ask more questions and give guidance as in general people have a bit of adrenaline when calling and might not be in the best shape to give a clear description. Immediately dismissing such scenarios could lead to some harmful results.
That's an interesting interpretation. They also said that "they were damaging cars" and "they became aggressive".
You should reread the comment, this wasn't actually said.
There are just too many cases where a quality of life type call like this (you haven't yet been actually beaten) or a white person feeling "threatened" turns into a major issue -> police respond, end up needing to use force, the thing escalates.
