It really doesn't look like that, I can count the number of Muslims and Africans that I see in a month in Rome on one hand. I actually don't even remember seeing one when I visited the touristic center last time, their presence was that low.Italy, this is what the capital of Julius Caesar's country looks like today ..
But yeah - replace the population and get the same results just as some liberals I know told me that the US could very well have been founded by Africans.
You wont regret visiting Rome
The Africans might come out again during summer IF tourist return to the city, currently they have no reason to hang in the city centre and they hate cold weather
There are very few muslims that actually want to settle down in italy, northern countries are the prize for social welfare. And italians are still more religious and the Vatican is here. they prefer the atheists of norther europe
If you're looking to escape multi-culti society for a bit then from Rome on down the lower half of Italy is pretty good living, you will just see a bunch of Indians who work the fields for the farmers. Which is annoying but they work and live while obeying the law and are low crime.
Covid laws aren't that bad at the moment, bars restaurants are open during the day too
If you take the train from rome up to the northern cities you will be swarmed with africans and muslims in public transport and near the trainstations though, their sole objective is trying to get into switzerland and germany so theyre all bunched up in the north waiting to jump to the next country ( there is also more money in the north to leech off of )
They hardly have any integrated immigrants, they are very transient so far. its completely different further north and west in europe. There are 3rd generation migrants there that should be fluent in the local language but still speak in their own dialect and are very radical
