Come on. If you are gay or different in some way and want to be accepted, then yes. Oslo is a great place. But it is a fact that they are rude, often very arrogant. I mean, I think it depends on who you meet or ask. But the first person I asked directions of when I lived in Oslo was rude and that don't make a good impression.

I would say that the people from the districts are more welcoming and many of them would gladly help you if you stepped on their doorway and asked for food or help being transported somewhere. I know this because I have lived in Oslo as well as out on a farm in a little farm community.
