Oh that's the line. The parent whose daughter was raped and the school board denied it did struggle with the police, and there have been some other threats as there are with many strongly debated issues. The violent ones at school board meetings are easily been handled by the local police. No violence is acceptable. But there are bullies and thugs who wish to shut down the freedom of speech of parents who speak out against the child pornography, anti-police teachings, and racism (such as CRT) being taught to our children in schools. These people far outnumber the individual cases of violence against school board members, as do the BLM and Antifa members who have committed violent acts. Yes, I know they call them "mostly peaceful protests" but if you are serious about dealing with crime you have to go after the major perpetrators. The teachers association apologized, and now it appears that there could have been pressure from the Biden administration.
