Even if the story is fake as you claim, there are too many other stories over the years mentioning the same behavior in those mussulman tribal societies. They are extremely barbaric with a civilized veneer for naive Westerners to oooh and awh over, which is more of Islam’s taqiyya.
La Monde could likely have came under extreme pressure to deny the story from the hordes of mussulman and French sycophants and assorted politicians. There is no way to prove it true or false - just claims. However, the claims are based on realities inside the mussulman world.
Sure there is. First of all, it's not our job to prove it's false. It's their job to prove it's true. There's no proof at all that Le Monde published such an interview.
"News" without verifiable sources is worth nothing. (That absence in itself should arouse suspicion. When I cite something -- and I'm just a guy making posts, not a news source -- I try to provide some direct quotations, and a link to the source on the internet or specific reference to a book. Look at the thoroughness with which I documented my post 46 and compare that with the article. These people are clowns. There's no link to any such interview in the oldest copy of the claim that I can find on the internet, and no direct quotations from it.)
If the interview really existed, someone somewhere would have direct quotations from it. I suspect that Le Monde slants its stories to the left (as do most of the mainstream media, both in the U.S. and France), and because of the paradoxical alliance of the Western left with Islam, would tend to excuse most things associated with Muslim societies. Still, whether reliable in general or not, it wouldn't have the nerve to deny that the interview had been published in its newspaper if not true, not when people could have copies of it, or have direct quotations from net copies, or graphic images captured from its screens or pages.
This fake princess-interview story is a blatant -- not subtle -- example of fake news. Few things are more obvious. The only mystery is who exactly is responsible for it.
The Fort Russ News article, though, is labeled this way -- "November 6th, 2017 - Fort Russ News - - Breakingnews.sy - - translated by Samer Hussein". So apparently Breakingnews.sy (an Arabic-language source) is claiming that such an interview appeared in Le Monde , or else the "translator" Samer Hussein is misleading us about that claim, or else the Russian Fort Russ News is making this up (and perhaps inventing the character of Samer Hussein -- translators aren't usually cited as sources).
Arabic-language sources don't have a very good record for truth (and if internecine differences will cause Muslims will blow each other up in mosques, I don't doubt that such differences could lead to lies too). Nor do the Russsians have a good record for "pravda" [truth ;-]. I don't know who's responsible for this particular hoax, but I'm confident that the attribution to an interview in Le Monde indicates that it's fake news.
(I agree that outrages such as the ones claimed in the fake interview may indeed be happening in Saudi Arabia -- and if not, there are many other things to criticize about that country -- but to cite fake evidence about it merely causes people to be more skeptical about more legitimate claims. As an anti-Islamist myself, I'm ashamed to be associated with this kind of stuff. Lying idiots don't speak for me. And who but an idiot would fabricate the claim that an interview appeared in a well-known newspaper such as Le Monde, when it can be easily confirmed that it didn't? )
