One thing that Americans have been doing since the election expresses their arrogance better than nearly any other attitude could. They seem to think of Canada as utilitarian but not very attractive clothing that they keep in the closet and think they can put on when the weather gets bad. Now many of them are saying (seriously or jokingly) that they are going to move to Canada, either individually, or as states.

That assumes they could. That assumes that we want them. I don't think so. If Americans move to Canada, they will bring attitudes with them that have made the US into a country that they now want to leave.

Americans often call Canada dull -- how on earth would they adapt to that dullness?
Americans (for the most part) think that a military response to a problem is appropriate, feasible, or permissible. Canadians don't -- unless there is no other choice, and everything else has been tried.

Americans believe in the right to bear arms. Canadians don't, and most of us don't want to have that right -- look where it leads.

Americans believe in the rights of the individual as virtually sacrosanct, above all else. Canadians believe in the sanctity and rights of the individual within society, and not at the expense of society.

Most Americans are too religious for us. Canadians are largely secular humanitarians, believing that living a moral and ethical life should not depend on the promise of a reward or the threat of punishment after death. Religious people tend to have narrower beliefs than secular thinkers, by and large.

If Americans want to come here and lead peaceful, unarmed lives that they find dull (what! no driveby shootings? no race riots?), I for one would welcome them. Nearly everyone I know is an expatriate American who has become a Canadian citizen, and who is an asset to Canada.

If anyone wants to come here, please check your attitudes and your guns at the border.

All the above IMO, of course.
