A Portland, Oregon, mother has filed a lawsuit against her children's elementary school, alleging that the display of an "Intersex-Inclusive Progress" flag and a gender identity assignment created a political atmosphere and constituted indoctrination.

Allison Roberts, represented by the Liberty Justice Center, expressed her concerns to Fox News Digital, stating that the "increased political presence with the progressive flag was a bit much" and served as the "final straw" in her perception of the school becoming a "political apparatus."

Roberts' lawsuit, filed last week, specifically targets Meriwether Lewis Elementary School's decision to repaint its traditional rainbow pride flag and an "identity flower" assignment. The assignment reportedly asked students to identify and discuss their gender identity with classmates and teachers.

Describing herself as a liberal Democrat, Roberts stated that the new flag was a step too far, particularly given her religious beliefs. She expressed concern that similar situations are occurring in schools nationwide, noting, "if it can happen here, I have no doubt that it can happen anywhere."

Roberts initially raised concerns with the school administration but received what she deemed an unsatisfactory response. Subsequently, she distributed an open letter to the community criticizing the school's policies on a public sidewalk outside school property.

Following a confrontation with another parent, Roberts was issued a one-year trespass order, barring her from attending school events, including her child's graduation. The school reportedly cited "harassment, intimidation, and threatening behavior" as justification, describing it as a pattern of "animus and harassment targeting vulnerable members of [the] community."

The Liberty Justice Center argued that the school violated Roberts' First and Fourteenth Amendment rights by retaliating against her criticism. Timothy R. Snowball, senior counsel at the Liberty Justice Center, told Fox News Digital that the school's actions were particularly concerning because Roberts' criticism occurred outside school property.

"Not only is that problematic for the First Amendment, but it really undermines our entire democratic system of government," Snowball said. "We have something called the marketplace of ideas in which each citizen is supposed to be able to participate."

Portland Public Schools declined to comment on the ongoing case.

Roberts encouraged other parents to engage with their children's schools and to "be loud" when necessary. "I think the time for hoping that the common sense and the adults will enter the conversation and make things right is kind of over," she said. "And I think it is time for us to be vocal and to get involved."
