Macnas is a performing arts group that had staged Halloween parades in Dublin since 2013. The COVID-19 pandemic stopped those parades until last year, but the group had not scheduled one in 2024.
That seems like a pretty f-ing important detail. The rest of the article and headline makes it look like a bunch of people showed up because of some random parade announcement, instead of people who were expecting an annual event and got some details from the wrong source.
Wow, what a way to take the most extreme POV possible on an issue.
