During this time of heightened political tension in the public sphere, I'd like to remind all of us that we must adhere to basic protocols of public speech and action. There is a reason why some forms of these (such as the nazi salute) are illegal in Germany, for example. They are too inflaming to be allowed in public space.
If you see or hear something, photograph or record it. The send it to your Head or President's office or, if you're worried about doing that, to me and I'll forward it. Let me know whether yo want your name included or not.
A very mild version of why this is important goes like this. What concerns me is what concerns me about how England and Japan address bullying in school. The general approach seems to be "we don't have any bullying, because we don't talk about it." Then someone commits suicide and the issue is in the news for a bit. Then they go back to not having any bullying, aka not talking about it.
