For example, should government track all Muslims? What if in 10 years the government started tracking all Christians?It certainly works as an argument but it's scary it even has to come up this way. It's basically having to explain to someone else: "You know, muslims are people too".
"It could happen to you" is a symptom of failed education of the recipient. It's scary some people today still lack basic empathy, the basic considerations that "all people are equal and deserve the same respect as you owe yourself".
Not to detract from your point, of course. It's more understandable that someone wouldn't immediately connect the dots between "Bad thing happening to bad entity" and "Bad thing could also happen to good entity". Although I'd consider it a similar failure of education as well.
