Just a thought

If you are a teacher with a sign in your classroom that says "Everyone is welcome here", don't resign if your admin says to take it down

Rather eat up their time in a long string of meetings to understand if it was the material, the font, the size, the ink color, ... until, they are like "OH FFS! TAKE DOWN THE SIGN!"

Then replace it with a bigger sign with bold letters that says "No One is welcome here"
Rinse, repeat
Then "Only Some People are welcome here"
etc.
