I think it's complicated. "Complaining" is different than "making safer suggestions". Part of decreasing
lawn toxicity is getting people comfortable with the idea of a "shag rug" lawn that shades the soil better and is better at out-competing weeds. Also key is helping people see the beauty in multi-species lawns. One way I've done that is to plant crocus bulbs in my lawn by the driveway where people will see them. If it were me, I'd consider printing out Paul's lawn article and taking it in. Show the great benefits to nature of changing how we see "lawns", possibly suggesting one area to start with?
