You will NEVER see signs at ANY Lobo athletic game, made by students or otherwise that say anything derogatory about a school being uneducated; or referred to by any other name than their school mascot. Nor should the Lobo principal have to appeal to the neutral site custodial services to take down a sign that the WH parents and teachers wouldn't take down. I was there.....I saw the sign.....I took pictures of the sign....we listened to the chants from the WH students at a volleyball playoff game. I also wrote a letter to the superintendent, explaining our disgust at the behavior of the students. The kids involved had to apologize but "they didn't mean anything by it". The apology never happened and the kids graduated. The only notice about the "incident" was on Twitter for a brief moment.
This is one incident among many, involving schools that have kids of color on their teams. So yes, complicit is the perfect word for the administration and parents. And if you don't see a problem with their behavior, then you are also part of the problem.
