Euros don't know liberal means different things in different places. I've only seen lemmy draw a huge distinction between left & liberal. I think it's the Euro influence.
In North America, they call leftists liberals & don't split hairs like Europe & Latin America.
In Europe and Latin America, liberalism means a moderate form of classical liberalism and includes both conservative liberalism (centre-right liberalism) and social liberalism (centre-left liberalism). In North America, liberalism almost exclusively refers to social liberalism.
People in the US get seriously confused that the Liberal party in other countries (eg, Australia) isn't liberal.
