The idea of donating alternative posters has already been tried and that particular school board just ignored the issue: https://www.npr.org/2022/08/31/1120239381/texas-in-god-we-trust-arabic-signs-chaz-stevens I'm sure they'd treat a donation of 100s of posters the same way.

And as I (not a lawyer) read the law it only says that a poster has to be displayed in each building and has to be donated or purchased with donated funds: https://capitol.texas.gov/tlodocs/87R/billtext/html/SB00797I.htm so I don't think you as an administrator would get away with plastering up hundreds of posters around your school, but let's say you did. The parents will complain to you AND the school board (i.e. your boss). They'll say you're making fun of their religion, you're a communist, etc. Even if they law was unambiguously on your side, they'll only see what they want to see. You'll find your chances of promotion to be zero, or you'll just be managed out. Even if the Board somehow agreed with you, you made a stink.

I have friends who are teachers and administrators, not in Texas, who have left or been kicked over lesser issues. The rest are looking forward to retirement.

These bozos passing these laws don't understand irony. They just want misdirection, conformity, and compliant kids. We just need to directly tell them to fuck off at this point.

I'm sorry for my continued Very Seriousness.
