an invader mosiac is not graffiti, it's street art, which is more or less the mortal enemy of graff. I'm not even trolling when I say people with attitudes like yours are what legit motivate so many graff writers out there.
the sheer lack of knowledge of the graff scene on HN isn't surprising in any way but wow there are so many idiotic hot takes in this thread hahaha. I've been writing graff for over 20 years - it's something the average civilian mind could never comprehend. Graffiti has existed almost since the beginning of civilization; it's primal, it's raw. Doing graff is one of the most human activities one could partake in. It's also one of the most pure art forms to be conceived. All of that is true and most graff writers are horribly toxic and terrible humans (most but certainly not all).
this is clearly a net loss for public health in general, politics aside. Having alcohol in dietary guidelines (without even stating a drink limit) is positively idiotic.
