It's about scale. A disagreement that should stay between a small group of people and often could be solved by mediation, a conversation, or community service ends up being a national event.

An individual who has a specialized skillset loses the ability to be economically viable. They might not be able to get another job in the field.

Often, they are being used as a scapegoat.

If you make it impossible for a person to get a job in his or her field because you disagree with what they say, that's a form of violence. If you're going to economically eliminate someone in a scaled way, make sure it's worth it; it should be a last resort. This is really about scale.
