The Springfield News-Leader.On Twitter, Wallis explained what happened and why he resigned.“At the beginning of the school year, I had two signs above my whiteboards that read ‘In This Classroom EVERYONE is Welcome’ and an LGBTQ+ pride flag on my bookshelf,” Wallis wrote. “This was an attempt to make my classroom more open and welcoming for all of my students, and nothing was ever taught about the flag because it stood there as a reflection of my classroom as a safe space for my LGBTQIA+ students.” Wallis said that a parent complained that he was “going to teach their child to be gay.” He was told to take down the flag and sign.“In fact, the use of the pride flag in my classroom was compared to hanging the Confederate flag in my classroom,”.
