Crypto jews (ashkenazi with European admixture) may look very European, but you can tell by examining the shape of their skull and body. Europeans are primarily Cro-magnon, while jews have a lot of neanderthal DNA. This causes big differences in our body, minds, and how we see the world. If someone exhibits one or more of these traits, be suspicious. 1) short or no neck - jews tend to have short, squat necks. Their heads will appear to sprout out directly from their chest. 2) ears that slant backwards with the top of the ear at or below the eye line - draw a line from the corner of their eyes back. If the ears are below this line, and the ears slant rearwards, watch out. 3) forehead that slopes backwards - this is a dead giveaway. The rearward slope of their forehead will often match the rearward slope of their ears. 4) protruding upper jaw and receding lower jaw - the upper jaw will protrude, but the lower jaw and often chin will recede. The lower jaw may look like it's almost part of the neck. 5) hooked nose, shaped like the number 6. Nose jobs aside, the tip of the nose will be lower than the nostrils, and there will often be a hump on the nose. 6) short body, wide hips - they tend to waddle when they walk.
