That wiki doesn't describe anything related to using the phrase for evil.

The wording isn't as strong, but I think this paragraph explains a bit what GP is talking about:

> Ethicist Jack Marshall described "Think of the children!" as a tactic used in an attempt to end discussion by invoking an unanswerable argument.[2] According to Marshall, the strategy succeeds in preventing rational debate.[2] He called its use an unethical manner of obfuscating debate, misdirecting empathy towards an object which may not have been the focus of the original argument.[2] Marshall wrote that although the phrase's use may have a positive intention, it evokes irrationality when repeatedly used by both sides of a debate.[2] He concluded that the phrase can transform the observance of regulations into an ethical quandary, cautioning society to avoid using "Think of the children!" as a final argument.[2]

> called the use of the phrase "Think of the children" in debate a type of logical fallacy and an appeal to emotion.[1] According to the authors, a debater may use the phrase to emotionally sway members of the audience and avoid logical discussion.[1] They provide an example: "I know this national missile defense plan has its detractors, but won't someone please think of the children?"
