These terrible slogans are the product of social media. A good slogan is only going to get juice from one side. A slogan that is supremely dunkable by one side yet scratches the itch on the other is going to surface like curds in spoiled milk.
What slogan have you heard is "A slogan that is supremely dunkable by one side yet scratches the itch on the other is going to surface like curds in spoiled milk". No slogan is going to be 100% perfect because it's compressing an enormous amount of political opinion and legal implementation into a few words. IMO "Defund the Police" worked because it got a lot of people talking. The detractors were bad actors and not actually interested in implementation.
