I tend to find that the "violent" people are outliers. Yes, I have raised my voice to councilmen, school board and other members when they are being stupid, but I try to remain respectful, and understand that people are trying, even if they are going about things different than many of us would like.
I actually have a lot of respect for what school board members have to do, and board members generally.
If we have to cater to people that think it is acceptable to cause violence and threats to others in our communities to get what they want, then we are lost.
