I am European descended, but I would not call myself a JBW coper. I would like to be proud of my race, heritage, culture, history, nationality, etc. And I am, to an extent. But not out of a sense of superiority to others who are of a different background; I don't think that is a logical thing to do and I would like to think I have a good understanding and appreciation of many backgrounds which are different from mine. There is no malice or evil in this and I think to an extent, it is only natural to have some in-group preference, but it only becomes wrong when one has a sense of superiority over others, a wish to impose upon them, or a disgust for others who are different to them.
But at the same time, as an incel it is also important to recognize that, as a consequence of certain aspects in modern society and modern times, even the groups to which I belong demographically have cast me out and rejected me. And for this reason I can never be 100% proud of who I am because they have cast me out and rejected me; they don't see me as one of them because of my looks and non-NT status.
Therefore these are good reasons for which I sympathize with other incels even if we share different demographic backgrounds, because we share very similar struggles. In this specific way, I am more similar to a currycel like OP than I am to one of my own relatives.
