This, and all the other extreme events happening all over the world, is exactly why these extremists are so succesful.
No, the core reason is that people "care" about some one thing, maybe two or free, which make up their daily news.
There are mass murders, catastrophes, climate disasters all around the world all the time. Instead of this "daily news" algorithm one should pick the area (maybe a few) in which they want to help and do that. Make it unpaid work instead of virtue signalling.
Also I'm not arguing these people are fascists, but there are fascists doing much worse things, like honest to God mass murders, today on our planet. Yet they don't matter, because this is Italy and that is brown people killing each other.
