Sarah Inama, a 6th-grade teacher at Lewis and Clark Middle School, has recently spoken out about her experience being directed to remove signs from her classroom that supposedly express a personal opinion.
Inama, in an email from the district, was told that her poster "conflicts with the intention of Policy and Section
33-138, Idaho Code, Dignity and Nondiscrimination in Public Education Act," and was instructed to "immediately remove" it.
The West Ada School District also says, "... this situation is not about limiting speech or expression but about ensuring consistency.”

Looking at the law, if anything the sign would appear to support it, in that the sign clearly does NOT say or imply things that are banned by the law
(i) That any sex, race, ethnicity, religion, color, or national origin is inherently superior or inferior;
(ii) That individuals should be adversely treated on the basis of their sex, race, ethnicity, religion, color, or national origin; or
Pessimistically, I suppose the sign might not "acknowledge the right of others to express differing opinions" such as "Everyone is not welcome".
