I think what you're noting is that analogies are powerful tools. They can create a deep visceral association between A nd B that strongly affects how someone feels about B based on their existing feelings about A.

Like any powerful tool, it can be misused. But it can also do great good when used well. We live in a world surrounded by fiendishly complex systems with layers of abstractions and deep chains of emergent phenomena. Our primate brains aren't geared to process the consequences of our actions in a space that far removed from the forests where we evolved.

Analogies are one of the best tools I know to let us do that. But we do have to be careful about which analogies we choose to believe.
