of course your intentions were good, I have never had any doubts about it
It was not criticism against you, obviously.
The problem is that, sometimes, there are (Italian or non-Italian) people who launch petitions, even with the best intentions maybe, which have not been drawn up seriously and with accuracy, and this might turn out to be detrimental to the cause of animal protection.
The targets of our petitions (local authorities, Government, etc.) often consider us as fanatics, or people who are unable to reason logically, hence we should do our best NOT TO let them hit us on our weak side, thus becoming vulnerable to their criticism and giving them the chance to say "the usual exaggerations by those nuts environmentalists and animal-rights activists!". We shouldn't allow them to resort to this excuse even for the tiniest details.
For example, the previous petition you mention (re: Sicilian Government) contained grammar mistakes in Italian even in its title, as well as "shouted" expressions (BASTAAAAA) that one should never use when submitting an official request to authorities. It is not a formal question: if we want our requests to be TAKEN SERIOUSLY, we must BEHAVE SERIOUSLY.
Then, the south of Italy IS NOT A REGION! The southern part of Italy is composed of several regions (Puglia, Campania, Molise, Abruzzo, Basilicata, Calabria and Sicilia), each one with its own regional council and government, as well as regional laws on animals, so it is absolutely nonsense to refer to southern Italy as a region. That's one of the reasons (but not the only one) why I wrote this petition is too general and, therefore, useless.
As to animal protection organizations, there are several that are officially recognized all over our national territory (LAV, Lega per la Difesa del Cane, ENPA, OIPA, AIDAA, etc.) but the one you mention "Lega pro Animale" is not so well-known: I live in southern Italy and have never heard that name. Through Google I found they are mainly active in the Region Campania (Naples), so they should mainly focus their attention on that area, reporting local cases that actually happened there, and not speaking of southern Italy in general. They probably do a great job in that local area but, if they know of cases of mass-poisoning of dogs, they should immediately report that to the POLICE, with full details on place and date, as there is a national law in Italy that prohibits that. Then, if the police do not do their job and duty, these animal lovers could launch a petition against THOSE POLICEMEN, THAT MAYOR, of THAT CITY, with all details and being able to demonstrate that they submitted a WRITTEN REPORT to the police, otherwise we are just joking (and the killing of animals is not something to joke with).
