they didn't mention it from long time ago.

I only really know that nobody put it on the infogalactic page. I didn't search that much. I didn't know if they'd mentioned it before or not.

I do want to know. I also don't want anyone to reveal anything they don't want to reveal.

If you know their ethnicity, you might start to prejudge for many things, that's why many people don't want to talk about it on internet.

That makes sense. I don't say things about myself online sometimes too, for that reason.

I think it's relevant though, especially in a political context. I heard someone explain it this way (quoting loosely) -- "When Obama wants to do something for the black community in the USA, it's obvious that he's part of that community, and that things that benefit black people also benefit him, his family, his children, etc. People get upset sometimes when people point out "that person is Jewish," but it's simply relevant in the same way. If you don't know that they're Jewish, you don't understand that they have the same sort of personal interest in US foreign policy towards Israel, criminalization of negative sentiment towards Jews, criminalization of participation in the anti-Israel BDS movement, etc."

This is one of the reasons I consider it important to disclose my own non-white ethnicity when discussing pro-white politics. Does it change the way people look at me and how they treat me? Yeah, and I think that's all normal and appropriate.

People might disagree with me about it being relevant, that's fine. I don't feel the need to change anyone's mind about this. I did want to go ahead and say something about why it matters to me here, though, since most people who replied seem to think there is no good reason to look for and share this kind of information.
