My daughter came to us on the first day of school telling us that one of her teachers had a cross and a Bible quote on the wall. I didn’t want to get my daughter into trouble by letting the principal know about it myself since they would attach my name to it and she might face retaliation. So I wrote to the FFRF, sent them a picture my daughter drew of the cross and the Bible quote (no phones in class, so she couldn’t get a photo).
Not only were they responsive quickly when I contacted them, within a few weeks, they sent an email to the school superintendent with all the relevant legal information as to why this teacher needs to take the cross and Bible quote down and without identifying who reported her.
I’m not a member due to some financial issues right now, but as soon as those clear up, I am going to join. They do good work.

Not a downvoter, but I’d be willing to bet that it is because many people are used to people saying similar things to what you have said, but in bad faith. The Internet is full of trolls and a genuine openness to having discussion with people with differing opinions is not to be taken for granted.
I wondered if that was the case. I don’t feel as strongly about it as OP, but the fact their their daughter felt uncomfortable because of it is a good enough reason for them to take action. I’m not a parent or a religious person, so I will never have to deal with this, but I was curious as both a teacher and a person new to online atheist communities as to what the line was for OP and also others in this community. I was just thinking that if I were a parent, the iconography would have to be something over the line (ex: the 10 commandments vs one of Jesus’s more humanitarian quotes). Obviously, my theoretical child expressing discomfort would be the line if that were the case, but it might be different if i were just to observe it in the classroom.
