EXCLUSIVE — A Washington father is suing his son’s public school district after he said his 10-year-old was taught about gender surgery during a Pride Month lesson despite the Christian parent previously asking the school to excuse his child from LGBTQ-related instruction.On Tuesday, Alliance Defending Freedom (ADF), which is representing the father, Konstantin Averkiev, filed a federal lawsuit against Lake Washington School District, alleging officials violated Averkiev’s First and 14th Amendment rights by refusing to provide notice and allow his son to opt out of LGBTQ-related lessons and other school requirements that conflict with his religious beliefs.The dispute began after Averkiev said he met with his son’s fourth-grade teacher at Henry David Thoreau Elementary School in September 2025 and requested advance notice and an opt-out from lessons involving LGBTQ topics, gender identity or gender transition.WASHINGTON SCHOOL REMOVES TESTOSTERONE VIALS FROM PRIDE DISPLAY AFTER DISTRICT SAYS THEY WERE NOT APPROVEDA father in Washington state is suing his fourth-grade son's school district after he was not allowed to opt-out of a Pride Month lesson that included the topic of gender surgery.
