If a Gentile has jew DNA they aren't gentile anymore.
The jew DNA corrupts and destroys the gentile bloodline completely if it is mixed and it can't be reversed as far as I know.
Jews can look White, Black and Asian but as you empower your chakra's and especially your third eye (the eye of Satan) you can recognize them easily without even needing to look at their physical attributes.
White jews for example have completely disproportional facial features. Normal Gentiles have balanced faces, but jews always have some kind of strange thing that makes everything disproportional. A big forehead, strangely small or big eyes, their nose obviously, a very bony face, an unusually tall face, an unusually broad face, a strangely small mouth, a strangely wide mouth, disproportionally big ears, unusually shaped ears.
That's only a number of physical malformities that a person with jewish DNA always has a couple of.
A gentile always has a nicely balanced face where nothing looks out of proportion. The face just makes sense.
If your third eye is opened you can recognize a jew by looking at their eyes. Their most defining feature that can not be hidden no matter how much plastic surgery or fake smiles they try to put up is their gaze and more importantly what lies behind their eyes.
You can see the true vileness of their odieus souls by looking at their eyes. Even people who don't have their third eye opened can sometimes get this feeling a person is vile by looking them in the eyes.
If you can see aura's it's even easier to recognize them. Their aura is so distinctly different from a gentile it's impossible to mistake them for gentiles if you can see their aura's.
Also most of the time a jew will be able to recognize you are a danger to them. Just as you can recognize them they can recognize you to an extend. However they can't act on that alone, but it's very possible for them to see they are dealing with a satanic soul.
A couple signs that can indicate they are aware of you to some degree is if they suddenly for no explicit reason avoid you or are evasive towards you. They will avoid eye contact. Or they can suddenly try to act very nice and you can feel an aura of fear from them. They will compliment you for no particular reason to try and remain unnoticed.
Those are some things I have noticed when dealing with jews in public. They can't openly show their jewishness so they try to remain hidden and will do anything, even go as far as play buddy buddy with a satanic person to remain hidden from the masses and act as the innocent weakling with no malicious intent, but their intent is always malicious behind this facade.
