I agree with you. Serious question: I wonder how far you take that. For example, for me, the Confederate US flag represented a favorite TV show as a kid (Dukes of Hazzard), the south (which meant cool accents and hospitality). Until 5 or so years ago I didn't know anyone still associated it with slavery. When will it be cleared for use again?
In other words, what is the bounds where a tainted symbol can or can't be used? Geopolitical border?
