I'm someone who has read up a lot on fascism and still finds it difficult to define clearly. Can you please explain to me how this kind of bill is "literal fascism".
I don’t have an answer to this, I’m just here to say that Italian fascist economic policy was explicitly corporatist, promoting big, sector-wide industry conglomerates, criminalizing strikes etc. It's no coincidence that large business moguls (today in the form of corporations) have strong preference towards fascist leaning politics.
Making boycotting a crime seems a lot like proscribing a political view. I doubt the law has been enforced this way - or enforced at all - but if you went to the grocery store, saw a product sold by an Israeli company and decided not to buy it on account of that fact you have now committed a crime punishable by up to 20 years in prison.
The reality is that the courts would never uphold the validity of this law, and it's not enforced because the legislators know it's BS.
