That's ridiculous circular logic. The story is valid because it's not being covered? Millions of stories are not covered by the news every day. A functionally infinite number of non-stories are not covered by the news every day. The non-coverage of a story has no bearing on its validity.

Your claim is also invalid on its face—the election theft narrative is being spoken about endlessly. Trump's claims are headline news every single day. A significant fraction of the population believe it. So to claim that the story is being "censored" is simply wrong on the facts.
