I'm acquainted with Sirje Kiin and know that she's a level-headed person. Therefore, I suspect that her remarks, here, are out of context and misleading.
In reality, it's impossible to generalize about Estonians.
The old emigrants -- the refugees -- are rapidly disappearing. Their offspring are a mixed bag: many have no association with Estonians; a few have moved to Estonia, studied in Tartu, and even served in the military. Some speak excellent Estonian, others; not at all. Some have an interest in Estonian affairs only at the local level, with the possible exception of "laulupidu".
We welcome new immigrants from Estonia and some have blended seamlessly into our fold; others for their own reasons, not at all.
"Back home", we're a curiosity. Who speaks tolerable Estonian is held in very high regard. Others -- the pretentious who say that, "mina oskan estoniani spiikida" -- are rightly called silly, behind their backs.
It's to everyone's advantage to develop ties among Estonians where ever they may reside. Independence and freedom are at hand, now. It should be put to good use.
