So yes, Italians do feel like the inheritors to the ancient Romans, just ask an Italian.
That doesn't mean they are. Continuity of geopolitical narrative is mostly stupid. In the era of nationalism (post-Napoleonic France) geopolitical narrative is 100% jingoistic propaganda: those impulses are 100% recuperated by the State.
By this logic, there are no inheritors to ancient Egypt at all since even the current inhabitants speak Arabic and not ancient Egyptian.
That's actually very coherent, or more coherent than the idiotic notion that because people live in the same place, they are connected genetically, culturally, linguistically, or politically.
You're discovering the complexities of comparing geopolitical strata across time and space. Don't disrespect it. Just because you have feelings about an essential "egyptian" storyline doesn't mean those feelings are valid. Shut up. Thanks.
also shut the fuck up you smug fuckhead
