I think being inclusive of viewpoints is incredibly important, even if they contain something factually incorrect, so I am not advocating some sort of thought police.
There will always be some fringe elements, everyone has a crazy uncle/aunt, but I do not believe for a second that anything close to the majority is crazy so the desired way to advocate an action is through agreement in the democratic process. If you can't convince and compromise maybe your opinion is not the right on balance for society.
What I am suggesting is an effort to protect the democratic process and that we do not let any group use extrajudicial measures to enforce an action. Anyone that treats it as war needs to see that this has consequences and should not be celebrated.
