A more thorough explanation:

Definition: Defamatory propaganda is the systematic spread of false information or rumors to harm a person, group, or government.

Propaganda is the dissemination of information to promote or injure a particular doctrine, view, or cause. Defamatory propaganda is a type of propaganda that is used to undermine government authority or promote dissatisfaction among a nation's citizens. It is often used in wartime but can also be used in peacetime to incite people.

For example, during World War II, the Nazi regime used defamatory propaganda to spread false information about Jewish people, portraying them as a threat to German society. This propaganda was used to justify the persecution and genocide of millions of Jewish people.

Another example of defamatory propaganda is the spread of false information about political opponents to harm their reputation and influence public opinion. This type of propaganda is often used in election campaigns to sway voters.

Defamatory propaganda is harmful because it can lead to discrimination, violence, and even war. It is important to be critical of the information we receive and to fact-check before believing and sharing it.
