To be honest, I haven’t seen the comment or criticism you’re referencing and even if I had, I likely wouldn’t have given it much weight. I'm not sure why you feel the need to highlight the differences between us, especially when, from my perspective, there are no meaningful similarities to begin with.
From the way you've spoken about mixed-race identity, it seems your understanding may be limited to individuals born in the UK parents with possibly with two, visibly distinct racial background.
In contrast, mixed-race heritage in communities such as those from South America and the Caribbean is often far more complex and layered. In those contexts, mixed heritage can include Black, Jewish, Indian, Chinese, Syrian, and various European ancestries sometimes all within a single-family line. Among those ancestries are both sephardic Jews* *, who fled persecution during the Spanish and Portuguese Inquisitions, and Ashkenazi Jewsi, who arrived under different historical conditions. Individuals can both national and ethnic identities; they identify with the both the country they are from as well as their ethnic origins. These distinct histories shape cultural identity in ways that may be completely unfamiliar to you.
This is why someone like you regardless of how you identify will likely have a worldview and lived experience that are worlds apart from mine. This isn’t a personal attack, but rather a recognition of how structural, historical, and cultural context shapes our differences. Your response only reinforces that reality.
Don't worry about mixed heritage or identity. It may be more constructive for you to reflect on your own experiences, rather than attempting to define or discredit mine.
As you are likely aware, mixed-race identity encompasses a wide spectrum of backgrounds and lived experiences. While I don’t always agree with every poster in this discussion, I can usually understand how their perspectives have been shaped. In your case, however, I neither relate to nor fully understand the approach you're taking and that, too, says a great deal.
