Jew by ethnicity or religion is irrelevant. Converts make up less than 1% of Jews.
From the point of view of a non-Jew (neither religious or ethnic), interested in the freedom & safety of his people, from Jewish Cabal plans, ALL Jews are in the club, in the same fashion as a non-Jew with a Jewish partner is in the club.
On balance, allowing them to remain, will see your people betrayed. Even if not in every instance, in enough instances to make it unviable to make a distinction.
There is no obligation of non-Jews, to treat Jews (ethnic or religious) as if they are anything but Jews, like all other Jews.
Jewish BEHAVIOUR is what marks them as a people, and makes them undesirable.
But this behaviour is carried out by both religious and atheist Jews.
Thus making distinction between them pointless.
The CULTURE remains, as does the possibility and probability of throwing other people under the bus for the sake of advancing Jewish interests.
The path for a Jew to stop being a Jew is relatively simple. Stop identifying as one, stop serving Jewish causes, stop hanging with other Jews, and earnestly do one's best to live as a White person, and serve White causes. Over a few generations, if earnest effort is maintained, the person's descendants will have ceased to be a Jew.
For a person born a Jew though, there is no path to being other than a Jew, in one's own lifetime. In the same way there is no path for a Negro to be non Negro.
And while there is no path for a Jew to become non-Jewish, they can be, from the perspective of other non-Jewish peoples, the possibility of them being a "good" Jew.
Which will be a Jew that world earnestly for the society he is in, and not for Jewish interests, and where his effort actually aligns with the interests of the majority in the society he is in, and conducts himself in a manner that is wholly non-Jewish, and that does not act to provide cover for bad Jews.
For instance, a genuinely good Jew would never say "not all Jews", or "it is unfair for a society to kick out its Jews", for he would understand that asking a society to keep its Jews, even just the good ones, is very likely to prove deadly or at the least, very harmful to it.
This may be tough for an individual good Jew to bear. Unfair even. But life never guaranteed fairness, and any tribe endeavouring to leave itself open to risk, to avoid unfairness to any party, will find itself abused to death in quick time.
Life for many goyim is unfair too, and other individuals of other species.. it is the way of the universe.
Again, it is not our place to make everything fair for all parties.
Judaism WAS a legal system. It is now a legal system, a religion, and ethnicity (race) and a culture.
And all of those things toxic from the root.
Each back to their own place is the best way, and then keeping up education and defences to refuse new entry points.
In time, if living in a nation of their own, and unable to prey on others, it is likely Jews themselves would culturally & biologically reform.
It has been their living separately within the lands of other people, that provoked such a negative outcome. Perhaps living in their own society, surrounded by just their own, could restore some normalcy over time.
