That’s actually one of my favourite parts. Not that such crap didn’t exist, but that it didn’t triumph.
Personally, I spent the entire weekend (far, far too much of it according to my SO) defending someone else’s national flag from vandalism - simply because they appeared to need the help more than my own, and I thoroughly enjoyed the absurdism.
This interaction between different ‘groups’ defending/promoting different ‘art’ was the best part, easily. Seeing various doodles have diplomatic struggles (and treaties & successes) with neighbouring doodles was fascinating.
