I'd like to shed some light on handshake convention in Sweden for the benefit of the thread. Handshakes are fairly serious business here, you basically shake hands whenever you're introduced to anyone. Not shaking someone's hand is considered very rude. Outright refusing to shake someone's hand is treated as a deliberate insult, and frequently used as such.
Like I mentioned earlier I work in healthcare. We oftentimes go out of our ways to shake the hands of patients even when they're in a medical condition that makes it difficult for them, like being paralysed, because doing otherwise would come off as discriminating and dehumanising. Some people even insist on shaking the hands of unconscious people as a sign of respect.
This is not the first time refusing shake hands has had national repercussions, it's just a one of a few cases where the person not shaking the hand wins. Other recent cases:

Non-religious example, intentional insult. Left Party MoP refuses to shake the outstretched hand of racist Sweden Democrat MoP in a session of Parliament. Receives national attention and leads to debate about acceptable behaviour in Parliament.
Tl;dr: handshakes are serious business in Sweden. Refusing to shake someone's hand is considered a sign of disrespect or intentional insult. Attitude not likely to change anytime soon even if alternative greetings ate used.
