Only if you agree that de Santis is, e.g., an ultra-nationalist. And if you do agree that all or most of those points apply to de Santis, then it's hard to see why you'd not agree that he's far right. I mean, who would be far right in that case? Only ultra-ultra-nationalists who are more-than-just-radically conservative?

To be clear, I'm not expressing an opinion here as to whether de Santis is far right. I'm saying that anyone who disagrees that he is will probably also disagree that at least one component of Wikipedia's definition applies to him.
