I'm Italian. On my side, I did what I could do: I emailed Italian politicians explaining why they should reject the proposal. A drop in the ocean, and far from impactful, but if it can change the odds even by an epsilon, why not?

Big politics is not my thing, so for me the big effort was: 1) understanding who, among the zillions of politicians we have, could have a direct role in the decisional process and how; 2) searching and collecting the email addresses; and 3) funnily enough, picking the right honorifics (for example, I was not aware that "Onorevole" is reserved only to certain figures in Italian politics).
I shared the resulting effort on my website, in the hope of making life easier for fellow Italians who want to do the same.
Thank you for sharing this, it saved me quite some time and I coincidentally found a great resource (your blog).
