It depends on the country:
There is a perception that Europe is much more liberal on [marriage equality support] than the U.S. The truth is that even within European Union (EU) countries the variation is probably greater than within the U.S. A 2006 survey puts the range from 83% in the Netherlands (much higher than in Massachusetts) to 12% in Romania and Latvia (lower than in Mississippi).
Britain and America are at the same tipping point of around 50 percent support. And both president Obama and prime minister Cameron now favor the reform (yet another thing they have in common). Cameron's coalition government has promised legislation making it a reality by 2015.
Also note how "partnerships" do not end up as a viable alternative to marriage. They are almost uniformly a mile-stone on the way.
