Bingo. That one drives me bonkers. I am tempted to tape a sign to it saying “Unless you’re a republican.” Or just “BS!” would do.
They used to have small stickers with a drawing of a screw to stick over the heart of those I heart bumper stickers. Something similar would be nice for these yard signs.
I've thought of printing signs to stick next to them that look like an award, like "First Place Virtue Signaler" on a blue or gold ribbon, trophy, etc.
