There are many chess players. There are many chess players playing very good. You don't need to promote the anti-semite chess player. You can also promote the one who does not propagate fascist world views.
Let' use the analogy for the sentence from Peter Thiel:
The statement that managers should know something besides management is not original at all. There are hundreds of people telling you that. It is common wisdom. I heard that 20 years ago and I am still hearing it.
So why promote Peter Thiel for saying that? There is no need at all to quote him. The quote is not original, nothing new, nothing special.
Nevertheless, the commenter decided to quote Peter Thiel on that and give him praise.
