Among my favorite signs seen at the Women's March in Austin, Texas in February of 2017.
"My ... doesn't need your attention. My classroom does."
(To avoid my site being hit by spambots, or some silly search engines lowering its rank because of a certain word on the sign, I had to avoid mentioning that word. It's a sad state of affairs when search engines force you to censor yourself, or they'll classify your website inappropriately and lower its rank.)
