I don't think it's reasonable to "demand" integration. What should happen is that the existing cultures should be open and welcoming enough so that new-comers want to take part. Also, I like the idea of immigrants bringing their culture with them (and in some cases, that may be the last representation of that culture) and welcoming people to learn about it.
Multi-culturalism should be about championing different cultures and not forcing everyone into a cultural homogeneity.

Yes, it is reasonable to demand people who come into a country adapt to rules - written and to a certain extent also the unwritten, of which Sweden has many - of that country. When in Rome, act as the Romans. This adaptation will never be 100% but that is not the point, what is most important is that newcomers learn to assimilate to such a level that the natives are open and willing to maybe integrate some parts of the newcomer's culture.
People who 'are the last representatives of [their] culture' can write a book about it while becoming part of their new culture since it is clear that their old one did not stand the test of time. They're much better off that way instead of living like cultural fossils for the likes of NPR and PBS to make documentaries about. By all means document what that extinct culture had to offer but life is for the living and culture is the commonly agreed upon set of rules how to live it.
Multiculturalism is a pipe dream, something dreamt up by people who listened to one too many version of John Lennon's Imagine. It has been shown not to work time and time again, it makes it harder for people coming in to a new country to assimilate and integrate because there is no clear target to aim for. Culture is not a fixed thing, it evolves through time by adopting new things and getting rid of old customs. Multiculturalism does not call for cultural evolution, it calls for revolution: here's a whole new culture, now deal with it. Revolution hardly every works and when it does it tends to go badly for those on the wrong side of it.
GP literally addresses your points. I think we’re very welcoming in most of Europe, adopt others’ traditions, and are not too imposing. Just, you know, leave women alone and don’t aim fireworks at ambulances.
Dismissing any amount of integration is chicanery. We’re pro-social creatures, and knowing the lay of the land makes your life better.
Why is the burden always on the host nation and never the immigrants?
