The "us vs. them" issue is something I'm addressing in my psychological therapy right now, as I often can feel threatened by parents, and in general don't get along well with peers, it's been kind of a cognitive development issue since early childhood. I'm planning on being a math teacher, so there really isn't much room within class to bring up too many very controversial issues, and even said I cannot teach social studies simply because there is too much room to input personal controversial opinions into the curriculum. However, what I was simply stating is that, the fact that some parents might complain is simply not enough to discourage me from doing something if I don't feel as if I'm doing anything wrong. I feel that it is obligation for students to be made aware that their participation in the pledge is optional and no consequences will come from it. My goal in the long term though is to find a solution into how to make parents more of a partner instead of a competitor, and not see them as threats. Many make it pretty difficult though.
