The only attack is a single phrase, referring to him as a "sociopathic billionaire". I don't think his status as a billionaire is questioned, so you must object to the use of the one word "sociopathic". Let's check the DSM-IV:

Antisocial personality disorder is characterized by a lack of regard for the moral or legal standards in the local culture. There is a marked inability to get along with others or abide by societal rules. Individuals with this disorder are sometimes called psychopaths or sociopaths.

Well, not exactly clear-cut, but I think a reasonable set of people, perhaps including Thiel, would agree that he has "a lack of regard for the moral or legal standards in the local culture"

Am I alone in liking Peter Thiel? None of what he's done, including the blood, seems particularly wrong to me. With the exception of supporting Trump. But I think he supports Trump because he feels influence on the man is underpriced considering his 20% chance of winning, rather than any love of his policies.

As far as I am aware he has never been diagnosed by a licensed psychologist. Indications of sociopathic tendencies are not evidence enough that he is a sociopath, diagnosis is.

Is describing someone as sociopathic really any different than saying that they have indications of sociopathic tendencies, though? If I describe someone as crepuscular based on when I see them active, it doesn't make them a short-eared owl.

"Drinking young people blood"?

[TazeTSchnitzel]

I recall that Thiel wants to get blood transfusions from people younger than him to prolong his own life.

Many of the apparently absurd claims about Thiel are, well, absolutely true. Indeed, this particular one was linked directly to a news article about it.

Drinking? No. Wants? Yes. That "Young people's blood" text in the article is a link that explains the reference quite clearly.
