Erik Marcus, undermining his own message, wrote:
"If every activist in the animal protection movement read and understood the Wikipedia link above [or here], we would collectively be vastly more persuasive and credible."
Sadly, Marcus doesn't seem to realize that persuasiveness isn't strongly correlated OR caused by an understanding of causal relationships.

Logicians are no more persuasive to the general human population than marketers. In fact, they're often less so.

Let's look up the Wikipedia entry for persuasion:
Persuasion is a form of social influence. It is the process of guiding people toward the adoption of an idea, attitude, or action by rational and symbolic (though not always logical) means. It is strategy of problem-solving relying on "appeals" rather than coercion. According to Aristotle, "Rhetoric is the art of discovering, in a particular case, the available means of persuasion."
Methods include appeals to reason as well as appeals to emotion, subliminal messages, seduction, peer pressure, etc.
