A message to decision makers at the Museum of the American Revolution:

STAND BY YOUR EMPLOYEES, VISITORS, AND VOLUNTEERS OF COLOR and DO NOT host Moms for Liberty's opening event at your museum.

From the M4L wiki page:

Moms for Liberty is an American conservative 501(c)(4) nonprofit organization that advocates against school curriculums that mention LGBT rights, race, critical race theory, and discrimination,[1][2][3][4] while multiple chapters have also campaigned to ban from school libraries books that address gender and sexuality issues.[1][5][6] The group began by protesting COVID-19 protections in schools, including mask and vaccine mandates.

Moms for Liberty has been criticized for harassment, for deepening divisions among parents, for making students' education more difficult, and for having close ties to the Republican Party rather than being a genuine grassroots effort.

Alleged harassment of and violent threats towards teachers and public schools
Critics have accused Moms for Liberty of deepening divisions among parents and making it more challenging for school officials to educate students.[1] Left-leaning Media Matters for America has accused the organization of using "parental rights" as a cover for strategically harassing public schools.[1][16] Jenkins, who replaced Descovich on the Brevard County school board, said that she was harassed by members of Moms for Liberty. According to Jenkins, a member of the group filed a false child abuse report with the county department of Child and Family Services against her.[1][16]

In April 2021, the Facebook group "Mandate Masks in Brevard County schools" (now "Families for Safe Schools") was founded in an effort to combat the Brevard County Moms for Liberty chapter.[17]

In June 2021, the chair of the Williamson County Moms for Liberty chapter told Tennessee's Department of Education in a letter that the district's curriculum was in violation of a recently-enacted state law banning the teaching of ideas related to critical race theory. Specific complaints were made about texts featuring Martin Luther King Jr., Ruby Bridges, Civil Rights Movement protests, and school segregation.[13][15][11] In November 2021, the Tennessee Department of Education rejected the complaint on procedural grounds.[18][19]

In September 2021, the Livingston County, Michigan, Moms for Liberty chapter head allegedly threatened the school board with violence, and said, "We are coming for you. Take that as a threat. Call the FBI. I don’t care," according to court documents.[20] The local chapter head now reportedly has a restraining order against her for stalking.[20]

Moms for Liberty was criticized for offering a bounty to members of the public who "caught" teachers introducing texts or lessons in violation of New Hampshire's new law restricting discussions of race in school classrooms. On November 10, 2021, the New Hampshire Department of Education announced a website questionnaire to make it easier for the public to help enforce the law. A couple of days later, the New Hampshire Moms for Liberty chapter offered a monetary reward for doing so, tweeting: "We’ve got $500 for the person that first successfully catches a public school teacher breaking this law".

According to The Daily Beast, a spreadsheet accompanying the Williamson County letter of complaint contained several other stated concerns about the county's curriculum. An article about police brutality against civil rights demonstrators in the 1960s was criticised for its "negative view of Firemen and police."[11] A fictional account of the American Civil War used with fifth-graders was deemed unsuitable because of its depictions of "out of marriage families between white men and black women".[11] A book about Galileo Galilei, an astronomer persecuted by the Catholic Church for theorizing the Earth revolves around the Sun, should, according to the spreadsheet, not be read without some counterbalancing praise of the church: "Where is the HERO of the church?", asks the spreadsheet notation, "to contrast with their mistakes? ... Both good and bad should be represented".[11] A picture book about seahorses was condemned for depicting "mating seahorses with pictures of positions and discussion of the male carrying the eggs."[11] The Williamson County Moms for Liberty chapter told The Daily Beast in an e-mail: "Some books should be removed entirely. Some books are objectionable only because of how they are presented via the accompanying teacher's manual. And yes, some books would be better suited to a higher grade level due to their age inappropriate content."[13][15][11][24]

In 2021, the Indian River County, Florida chapter requested the local school board remove from school libraries 51 books the group "deem(ed) to be pornographic or sexually explicit."[8][25] A critically acclaimed[26][27][28][29][30] young adult book about growing up gay, All Boys Aren't Blue, was pulled from the Vero Beach High School library after the group objected to it as being in violation of a Florida statute against providing access to pornography to children.[25] The Hernando chapter objected to Looking for Alaska, The Absolutely True Diary of a Part-Time Indian, and two books by National Book Award winner Alex Gino.[31]

In December 2021, the Wake County, North Carolina chapter filed a criminal complaint against the Wake County Public School System over the books Lawn Boy, Gender Queer: a Memoir, and George.[32]

According to WFTS-TV, as of December 2021, "several schools" had removed books from shelves due to the efforts of various Moms for Liberty chapters.[22]

In June 2022, Cabot, Arkansas Police opened an investigation after a recording surfaced featuring one of the group's leaders, Melissa Bosch, fantasizing about shooting school librarians, saying "they would all be plowed down with a freaking gun".[33]

However, Moms for Liberty has partnered with several conservative organizations to introduce conservative books into public school libraries.
