So I’m Wiccan, and while if pulls from things, and arises out of an occult millieu much older than it, Wicca is essentially a modern religion. The Wheel of The Year, the Wiccan liturgical calendar, is newer than the labor movement’s establishment of May 1st as Intl. Worker’s Day.
Beltane, was originally a Gaelic holiday Marking the midway point between the Spring Equinox and the summer solstice (and its not even what the Holiday was originally called in Wicca btw).
It makes sense that a general spirit of resistance would come from working class Irish and Scottish who sat on the periphery of English Industrializations benefits, and were more easily exploited as cheap labor. And it makes sense that they might latch onto an existing springtime festival as a date for a radical workers holiday. Spring means new birth, perhaps even of a world beyond Capitalism.
Also some important labor movement events happened around that time of year, most famously the Haymarket Affair, Which had a huge impact on the son selection of May 1st.
So I don’t think it’s at all bad that international Workers day, the culture of a historically colonized people, and pagan springtime holidays, both ancient and modern, all coincide and intersect. In fact I think it’s a beautiful thing.
It’s like looking at Pride month, and Juneteenth in the US, and asking why gay people stole June from black people. They didn’t. Two oppressed people groups in the US experienced seismic events in the history of their liberation during that month. And that’s sick as hell!
Tl;dr - yeah, mentioning may 1st as also being a pagan spring festival is cool too

Because I’m active in my local organizing circles, and I see this stuff.
The No Kings folks aren’t doing that. Folks in various socialist orgs like DSA and PSL are doing that work. Folks in the unions, especially folks just starting unions, or are in reform movements within larger unions, like the UFCW or the Teamsters, are doing that work. Hell, the punk kids in our local Food not Bombs chapter always show up to pickets with food.
The folks organizing the No Kings protests themselves are not doing this kind of nitty gritty organizing work. They’re in a wildly different sphere. And my friends across the country mostly echo this.
That’s not to say they’re useless, or that people shouldn’t go, they should. But what I am saying is that the real, long term work, that sustains movements, is being done elsewhere. The more serious organizing that is happening at No Kings, happens not because of the No Kings folks themselves, but because more established, more radical groups are going and doing entryism and political agitation.
I don’t mind a big protest march, I’ve helped organize a couple (much smaller obviously lol) protests myself. But you also need to build power and leverage beyond that too. That could be through labor organizing, mutual aid, etc. But you gotta do more than “Raise your fists and March around, but don’t take what you need” as the Rage Against The Machine song says.
