Maybe it's instructive if I tell some things about how my ancestors fared. The leadership of the newly risen countries after WWI also wanted to create its own national elite. (Elite, in a wide sense as educated people, not as company owners/aristocracy.) In Romania, this meant ethnic quotas at higher schools (which hit my grandmother and her siblings who came to Budapest for that reason), and job offered to people in fields like foresty manager only away from home, in ethnic Romanian-majority areas (which hit my grand-grandfather). In Chechoslowakia, a similar ethnic rule was imposed on public servants. My multi-lingual grand-grand-mother (on another branch) chose to be Hungarian (tough her writing shows that wasn't her best mother tongue of three) and was fired, her son too, but all her brothers and sisters chose to be Slowakian and kept their jobs. Letters I have prove the old people continued to stay in touch, mostly in Hungarian, but the descendants fully assimilated to the respective nation.

I looked at your blog, and happened upon an earlier post I can't now find again where you and a lot of commenters discussed the intra-Hungarian xenophoby and the double citizenship vote. (BTW, the existence of such xenophoby is another proof that nations and ethnics aren't as straightforward things as people usually assume.) If you are interested, I wrote a diary here about the double referendum - tough it was focusing on the hospital privatisation issue, I go on detail on the other too. (I was a stop-privatisation-Yes, double-citizenship-No voter, but for none of the arguments all the parties shamefully campaigned with.)

If you read that, let me emphasize some things. The far-right Hungarian-Hungarian commenter with the 'Varangy' handle was way off blaming a leftist No vote for their failure: "Yes" won, the referendum foundered on participation, not a No vote, with the majority of Fidesz voters staying at home. So he should have looked at the target audience of the government's xenophobic campaign in his own camp. So much so that while normally I'd ask whether your observations of two behaviours correspond to the same sub-set of people, I feel fairly sure that the "poor oppressed Magyar brothers"-talkers and those who look down their noses are often the same. (Hungarian 'leftists' are more likely to not travel at all to Erdély, or only for tourism or visiting relatives rather than observing an ethnic reservate.)
