Panels from All Star Comics #4 (March-April 1941), script by Gardner F. Fox, pencils and inks by Everett E. Hibbard
Flash leads by example! I mean, not the dressing up in red and blue tights and wearing a salad bowl on your head example, but by teaching how to resist the snakes within our midst! In other words, he's rousing up the general public by teaching them about the terrors of loathsome hate literature. Also: knowing is half the battle!
Remember: to successfully and morally resist the forces of fascism in our great country, do not have the wool pulled over your eyes. (Exception: the great hero Sheep-Man.) Also, play darts with guns! No, ignore that last one. Just don't stand still twiddling your thumbs when you hear hate speech, no matter who it's coming from. (There is no exception for the "highest office" in the land, by the way.) Isn't that right, Flash?
And that's what the Flash will always believe in: truth, equality, and tolerance for all people regardless of nationality, with zero tolerance for racial slurs
OH FOR PETE'S SAKE JAY YOU WERE DOING SO WELL UNTIL THAT LAST PANEL
