It’s just people essentially saying “Look at ME! Look at MY VERY IMPORTANT OPINION!“ like a toddler trying to get their parents’ attention, totally unaware that no one actually cares what their opinion is. The near-total lack of self-awareness is kind of amusing. No one thinks that yard signage actually influences anyone’s opinions… placing them in one’s yard is an inherently narcissistic act. Just let these people be losers, man. Complaining about them just makes them feel validated, and gives them reason to perceive themselves as victims of what they probably believe is attempted censorship. They want your attention…stop giving it to them.
