There's no serious territorial rivalriy today, not even for the monolingually Swedish-speaking Åland Islands. Sweden's latest actual territorial dispute was settled almost a hundred years ago when the League of Nations decided that Åland should stay part of Finland. As for the rest of the question, I'm not sure I understand what you mean.
I didn't mean there's still territorial rivalry but when you are on a bilingual territory maybe you can identify more with one language than another so I was wondering if people that speak swedish in Finland maybe can be considered "less Finnish". You know, like people making jokes about Canadians from Quebec because they are "more French".
