Multicultural versus monocultural societies and countries

[Gilrandir]

I beg to differ. The majority of the French language is derived from a single linguistic set. The English language has several distinct sets of rules and customs, including famously farmyard animals whose name changes depending whether you're looking after the animal or eating it.

Slough (pronounced sl-ow, rhyming with plough): a town in southern England.
Slough (pronounced sl-uff, rhyming with rough): a layer of dead skin tissue.

The mixed character of a language's origin can't be a clue to determine how mono/multicultural is the present-day society which uses it.

The “holodomor” was not against an ethnic group as it killed as well Russians,

It was aimed against the whole of Ukraine, no matter people of what nationalities inhabited it. The borders of Ukraine (albeit only administrative at that time) were sealed so people from Ukraine were not allowed to leave it and very often they saw no famine outside it (for example across the river in Western Ukraine - then a part of Poland - or in Russia).
And finally:
@ all participants of this discussion:
You may argue back and forth, but the problem is that whether you want it or not, multiculturalism (as a trend within globalization) is here to stay and exacerbate. Period.
