Yes, but since the US is a more right-wing country than the rest of the developed world (healthcare, death penalty, taxes...), that would mean the Democrats are "centrist" and Republicans "right." Characterizing based on relativity to the developed world seems much more fitting, since we're discussing it between people mostly from other developed countries and in a thread about Britain.

Right wing on what measure?

With abortion restrictions in Europe, Europe looks further right than the US or Canada on that issue.

[reducesuffering]

By all three measures I mentioned above?

When it comes to abortion, it's more of a wash. By one measure, US is now more decentralized, less federal gov., thus more right wing. 13 US states have complete elective abortion bans at all times, thus much more right wing. Most other US states have somewhat more lenient abortion laws, roughly ~6 weeks longer in general, thus more left wing.

If that's your best and only example, it only substantiates my case.

And Canada has no restrictions whatsoever on abortion.

Now do attitudes towards immigration and multiculturalism.

I’d argue Canada and the US are more “left” of Europe on that issue as well.

You brought up Canada, Canada being more left than US just furthers my point that US is more to the right than over developed countries. As to comparing European countries to the US on immigration; % of immigrants in the country

Switzerland: 29%

Sweden: 20%

Germany: 19%

Austria: 19%

Ireland: 18%

Belgium: 17%

Norway: 16%

Spain 15%

*US: 15%

Netherlands: 14%

UK: 14%

France: 13%

Denmark: 12%

Italy: 11%

US doesn't seem like any sort of above-average on your chosen metric either...
