I'm no linguist, but the question does seem unambiguous, or quite clear, to a reasonable observer. The context is "voting in a US election" AND the subject is "an illegal immigrant" WITH an assumption that the illegal immigrant has, in fact, illegally emigrated to the US.
I love that you include the BNF-ish grammar. Grammars are so straight-forward to read, I wish my eyes didn't glaze over during those times I've tried to sit down and create one.
That doesn't only exist in Victoria and that busy-body group isn't only about building and housing. They are active against many things. I live in California and they complain about people walking down the street, water restrictions, lifting water restrictions, cleaning your driveway with water, not being able to use water, it goes on and on.
It does touch on building, but it's mostly about, "NOT IN MY BACKYARD!"
There’s a certain street in SF across from a shopping mall where there are fatal accidents involving pedestrians every year. Consequently, the city planned on building a crosswalk. Well, the NIMBYS blocked it because it would ruin their view.
I would agree. The saying, "Idle hands are the devils playground" can be appropriated as, "An idle mind is the fertile soil of the depressed."
Although the reality is the mind is anything but idle for those predisposed to depression. The rumination, negative thought patterns and self-critical thoughts are worse than a prison sentence of solitary confinement.
For those who may not understand this, imagine standing over a 5 year old constantly berating them, in a horrifically negative way, for every action they take, good or bad. Now imagine the effects of that over years or decades.
This cannot be overstated - the uplifting effect of the written word feels much more potent than hearing it from a friend or scouring YouTube videos.
I have found this book (https://tinyurl.com/4k27x6s9) to be a wonderful resource. I know there are many more to recommend, but I would start with the basics.
