To be honest, I don't know about Dekker. Still, I don't know a single person who is familiar with Ashkanazic Jews who could look you in the eyes with a straight face and try to assert that neither Gasser nor Brust or Kaminsky are at least partly Jewish (fully Jewish in the case of Gasser and Brust.) Perhaps I should have been more clear; I never meant to say that having a "Bible-inspired" first name implied being Jewish. But when you have a guy like Joshua Gasser or Benjamin Brust who is already red-lining the Jewdar, when you add in a name like Joshua or Benjamin it's like icing on the cake, for people who know Jews. Gasser (whose last name is almost certainly an abbreviation of a Germanic/Yiddish surname) looks as Ashkanazic to me as Bismack Biyombo looks African. A handsome guy, no doubt (Gasser). Most 'Jewish' last names could go either way - there will always be a plausible deniability in that regard. This is less of a science than it is an art. I've seen a few sources asserting, and none refuting that Gasser and Brust are Jewish. This whole topic branched off in response to a poster who lavished Gasser and Brust with compliments in the same post as he denounced all Jewish people as scum, or something to that effect. I had to point out the irony. When I mentioned Konig "passing the eye test," I was speaking from the perspective of a Goy.
