I’m rather fond of the Most Canadian Protest Sign Ever: “I am quite upset about this.”
I Think Someone Needs A Change
I can’t find it on the interwebs, but my favorite sign ever said:
[spoiler]Jesus is Coming
On your Dad’s Back![/spoiler]
Fuck, I laughed!
I liked the toddler at the Women’s March who was carrying a sign she had made herself. It had random squiggles all over it.
How about “Agent Orange is Toxic”, accompanied by a well-known hairdo.
How about a counter demonstration with signs that say “DOWN WITH PROTESTERS”. 
Go with the most extreme option
“Assad is a more moral leader than Trump”
If you can read this than your more literate than our president.
Every time I go to a rally or march I’m tempted to bring a sign proclaiming “Four legs good. Two legs bad”.
Or something similar, in a speech-bubble, coming from a pic of Trump. 
Along those lines, how about something referring to “President Dump”?
But do spell check it before you take it outside.
Not a sign but there is something funny about shouting “Starbucks is anti-black.”
There was a “Too little too late” sign that missed the opportunity of “Too latte too late.”
(Not to derail the thread. Personally agree that a bunch of white women wouldn’t have gotten the cops called on them. But then again I can’t see meeting somewhere without buying a little something.)
When it comes to protesting Trump I don’t know if I like putting that kind of language on a sign.
Maybe something simple like “Return to Sanity.”
“Ignore Previous Sign”
