Personally I teach adults, so in my capacity as a teacher, parental concerns are not my concerns.
In my capacity as a citizen of this country and as a taxpayer, I also don't care about busybody "concerned parents" who feel the system is failing them personally. My concern in this capacity comes down to how the system is building a better community for everyone. Individual parental concerns shouldn't turn into culture wars.
What I'm trying to say is that when it comes to their own children, they are not being "busybodies". It is their right to voice their concerns, and it is the duty of educators to listen to these concerns and take them seriously. You can't just brush them off. Even if the parent is being unreasonable, it is part of your job description to make them see reason.
Sorry, to be clear I teach adults, so it's not part of my job description to make any parents see reason. The concerns of one adult do not impact the way I teach any other adult, no matter how they are related.
As for my role as a citizen, I'm thinking specifically about my local community, which is beset by people who have very loud feelings about certain books existing in the school library. A lot of communities are facing this issue.
I call these people busybodies because nothing that they do or say is based in reality, but only on their feelings. It's feelings all the way down just, like the linked blog post. All they're doing is making everyone's lives harder: other parents, teachers, administrators, and especially the students. For what? There's no actual problem being cited. This is all to quell their own feelings about books. That's pretty much the definition of being a busybody.
