There's a curve to most people's response to levels of advocacy. The response rises with advocacy to a point, but then past a certain point, the response drops precipitously. When the advocacy turns into over-the-top vehemence, people tend to stop responding and may even respond negatively (i.e. rebel and go full anti-whatever).

As an example of a similar drastic falloff at the top of a response curve, I recall reading that people who live right next to a dam report near zero concern about the dam collapsing, but as you go further away people are very concerned, then somewhat concerned, than only little concerned.

So anyway, we need more carrots, fewer sticks.
