Let's think about what shouting a message to the world does. First, you affect the stakeholders of the decision-maker (person or organization). When talking about a politician in a democracy, the public often determines whether they get elected. So, you are applying pressure to them through a stakeholder — “fall in line or risk your career.” You are also slowly changing the culture and applying pressure to the societal outlook. This also applies to your decision-makers (whose friends, family, co-workers, and political or corporate partners partake in the broader culture) and future decision-makers raised in the culture you are shaping. These are all tactics you can use, but some decision-makers are very resistant to societal and stakeholder pressure. They either have a strong negotiating position (like Donald Trump, who offered Americans many things other candidates were not offering for moral reasons), or they may have a model of functioning in the politico-organizational system that insulates them from the ideas of others (they may simply be narcissists or zealots). But if you speak with them and you negotiate in terms relevant to them, they will listen. To that end, you first have to make the call or get in a room with them.
