your fascist fucking grandpa is literally Mussolini

That's not Meloni, I think you might be confusing her with Alessandra Mussolini. Even then, I don't think it's fair to hold people accountable for the actions of their ancestors, even when said ancestors are dictators such as "literally Mussolini".

and it's one of his old colonies

If anything what made the country so destabilized, ultimately leading to Gaddafi's rise, was the "liberation" (read as neocolonialism) brought by the British. A similar fate happened to all the other former Italian colonies such as Ethiopia, Somalia and Eritrea.

I'm all for the right of self determination of people and decolonization was a traumatic process for many African countries (think of French Algeria for one), but it's probably not a coincidence that all of those territories are now failed or war torn states. A smoother and more democratic process after WW2 might probably have helped the regions, but it's not fair to blame Italy for it's lack.
