Drogan's Encyclopedia - We Ain't Wikipedia
Wikipedia, the propagandist's encyclopedia, does cover left-wing extremism (redirected to far-left politics). However, the "far-left politics" article contains less than 1000 words. Conversely, the article on "far-right politics" contains almost 7,000 words and has numerous examples indexed by country. Within the article, several links are provided to other articles that provide examples of right-wing extremism.
It should be noted that Wikipedia and the Wikipedia editors are left-wing and sympathetic to left-wing causes, even that of extremists. Note the differences between the two public figures as described on Wikipedia.
Greene is immediately dismissed as some sort of lunatic. While Greene is known to be quite eccentric, she is rarely covered fairly and most of the Wikipedia sources are sources who are sympathetic to left-wing politics who have an unnatural antagonism for her. Conversely, Bill Ayers participated in the bombing of the New York City Police Department, the United States Capitol building and the Pentagon (in 1970, 1971 and 1972 respectively). This confuses many because Wikipedia and the Mass Media have repeated the false claim that the January 6th riots were the biggest attempt to overthrow the government that ever occurred on American soil and that no one has ever seen destruction at the Capitol building like this before in recorded history.
Notice how Wikipedia does mention Ayers sordid past (although it got it wrong as Ayers was bombing places well into the 70s), but Wikipedia downplays it by showing the great things Ayers does today by using the educational system to indoctrinate the youth. On the other hand, Greene is presented as a personal with no redeemable qualities who is a threat to society in general.
