In the US we got a head start on it with climate.

In Poland, I first started hearing it around vaccines and climate discussions couple years before COVID - but that may have been because I was hanging out in various social media groups discussing those topics (and/or just mocking the "science deniers"). The term however seems to have exploded in use since the pandemic. I think it's because it suddenly became relevant to mass audience and journalists started using it.

was that in Polish? if so, what is the Polish version?

There isn't a set one. "Antynaukowy" (lit. "anti-science") is the most common I've seen, perhaps because it's close to a well-established term "antyszczepionkowiec" ("anti-vaxxer") - but most often, it's just any of the expression that contains the core term of "anti science" or "denying science", such as "antynaukowe poglądy" ("anti-scientific beliefs"), "zaprzeczasz nauce" ("you're denying science"), etc.

Lol that last word has a z, a prz, a cz, and a sz.

They should really switch to Cyrillic!

I see this argument raised quite often and it's a bit like saying English should have it's own alphabet because latin alphabet wasn't made for whatever amalgamate of languages modern English is. There are cultural factors at play as well, Poland was historically a Catholic country and that came with latin included. Basically: digraphs are prevalent in many languages and Z is as good a letter as any.

Wrt. English, it still technically has stuff like Æ, so it too may just as well switch to Cyrillic.

I’m confused by both of these replies. Wasn’t Cyrillic created expressly for Slavic languages? And isn’t Polish a Slavic language?

Other than not having to use diacritics, what benefits does it present for modern Polish users to switch to an alphabet designed for Old Church Slavonic?

also how would it look politically

In the US,this went mainstream for the pandemic. It was an existing undercurrent in different communities.

Reactionary people weaponized vaccines with Gardasil - good Christian boys and girls are chaste until marriage, so vaccination is unnecessary. Sinners get gods punishment.

Crazy left-wing people cling to the autism rumors about vaccination.

All of this is magnified by politics and propaganda. Certain religious sects punch above their weight because of political factors - you can usually correlate this with measles outbreaks. Foreign influence operations encourage and stoke this stuff to encourage general unrest as well.
