Remnants are that which is leftover from mainly sewin projects. However, the remnant strand is seen throughout Abrahamic scripture as those who are left over after some event. They are people who understand themselves as chosen to be called in a different way. This "chosenness" is often looked upon as arrogance; however, those who believe in remnancy also know that all are chosen in the same way.
Unfortunately, only about 2% of contemporary Christians have accepted remnant theology into their lives. Our society and the world is full of people who have a need to use religion as leverage over others that they know. Christians, specifically contemporary evangelical Christians, are the most frequently used example of hypocritical living when claiming a belief.
Remnant believers do not accept or believe in self-appointed or unaccepted/pre-chosen religious leaders of any kind. It wouldn't matter what the person's title was. The answer to a self-appointed unasked for religious leader is that it is presumptuous to assume that a believer wouldn't have a relationship or understanding of a deity already. Not one person knows what another is to be doing in hi/her life or what he/she will be called to do at any point in time. Attempts at changing the believer's life, especially through behavior modification, is specifically hostile. There isn't a way to know what is going on in anyone else's life, regardless of intuition, without actually talking civilly with the person while attempts at changing the narrative are left behind. One person's narrative doesn't have more leverage or importance than another's narrative when the dignity of every person is upheld within the imago Dei.
While it may seem odd to people, people usually don't accept remnancy out of a means to remove accountability from that person's life. However, what it does is uphold the dignity, respect, and divine spark held within each person. Remnancy and the power structures that go hand in hand with it is often chosen by those with genetic connections to the Jewish people without choosing the denomination line of Messianic Judaism. The traditions are quite different, while like most denominations, are similar in some ways.
Remnant believers are not overtly known to those around them unless specifically asked about the person's life. There isn't one way to be remnant other than to be leftover. From what? Generally, the destruction of the Temple in 70AD. The closest thing to remnancy in the Jewish world, as far as I am aware, would be an egalitarian reconstructionist/reform Noahide. Such a thing/category doesn't necessarily exist as reconstructionists don't necessarily accept chosenness as far as I am aware. Christianity has remnancy which most people don't know about.
So where in the world are the remnants? We are everywhere. There wouldn't be a need to discuss it necessarily unless conflict has arisen. There isn't much to discuss beyond power use and specific boundaries. It does not, however, have a place for one person to remove and replace what another believes in any way shape or form. The use of replacement power is seen as directly antithetical and inhospitable to the remnant believer. It denigrates the very spark of life given to each human being. Some would even call most remnant believers as: particular. Contemporarily, conjectured jokes about OCD would be made concerning the individual when the use, which is abuse, of replacement power is used in the person's life. Often, remnant believers are told that they have "burnout" or that the person is just over-reacting when they protest the use of replacement ideologies. For those with a genetic Jewish link, it is a form of ethnic cleansing due to religious adherence. Remnant theology accepts genetic ethnicity as God-given along with other scientific facts about each person. God gave me my beautiful blue eyes.
Remnancy embraces and values the entire person to include the body. Along with the body comes the very DNA and genetic information that is often refused from both sides of the Jewish-Christian dichotomy, and without it, a person would not be completely whole. In short, remnant believers are often the conscientious objectors to causes except through educational and pacifistic social pursuits. Instead of a protest, a remnant believer would write to protest through poetry, music, and the like instead of carrying a poster to protest through civil unrest. It's a slightly different approach to the same social issues and civil concerns. Due to the difference, it is assumed that the person wants special treatment. Unfortunately, the treatment received is normally othering of the person along with defiant diagnoses.
Unity is easy when people have respect for one another. When people really focus on radical hospitality, community can be achieved without needing others to change to one point of view over another. The inclusion of the ger brings with it challenges, but it also accepts that others may be quite like us. It doesn't convict or condemn without reason or work to create one.
