What is your criteria to be a member of your ethnic group?

[Creoda]

Do you believe that people with zero or a minority of blood from your nation can really be one of you? Do you think that your ethnic diaspora are part of the same nation or separate? How much foreign ancestry is acceptable? How much non-European ancestry is acceptable? How much of a role does language and culture play? For Colonials, how many generations does it take to be a true Australian/American? etc etc

Generally I think it's absurd for anybody who is ancestrally less than 50% of an ethnicity to be considered a part of that group. I think blood from closely related nations and cultures counts for more than more distant ethnicities, and especially non-European groups, from whom significant ancestry is a disqualifier.

Honestly I don't consider myself a true Aussie, my family hasn't been here long enough. I also don't consider people who are majority non Anglo/NW European to be true Aussies.

In Brazil just 1 generation. If proper Latino (American or European), sometimes he get along in years. Maybe some weird exceptions can take more time, but overall speaking I even know muslims that act more like brazilians after some that than anything else.

cant really answer because im mixed myself and it seems to be a question for pure europeans. serbs seem not to consider me as serb because im genetically to different and dont look like one of them. roma seem to consider me as one of them they consider that half hungarian woman in fidesz party as one of them many famous roma have extra european ancestry sometimes people dont even know they do like ricardo quaresma. but a half african would probably be a afro roma like ayo half nigerian half romanian roma she is termed afro roma.

To not be circumcised.

I'm genuinely interested in other's opinions here. In ethno-states such things would have to be addressed, and I want to know where people draw their lines.

Mentality and, to a lesser extent, the native language. Some might argue that the two are closely related.

Most ethnic Russians in Latvia don't pass because you can tell they think differently by the way they speak, even if it's in Latvian. It's kind of hard to relate in such cases.

In Maghreb being Muslim and talking in dialectical Arabic, French, or some Berber variety makes you full Maghrebi.
A Sino-Norwegian guy who converts to Islam and grasp some of the previous languages I cited is more Maghrebi than me. Feels bad man.

[Cristiano viejo]

Going so further that your generations can not be traced, being all these known generations of your own ethnicity.
