Why are all atheists liberals?

[Dystopia]

I would go one step further and say that both conservatives and liberals nowadays are both liberals because their ideas are based on liberalism, capitalism, democracy and individual rights - Liberals may favour a little bigger government but they want to get the government out of people's lives as a general rule (i.e. Liberals wouldn't nationalize the entire economy). There may be some differences between conservatives and liberals but both in america and europe they favour capitalism, globalization, free trade, free enterprise and individual rights. Because of that we are all liberals to some extent, at least because we base our beliefs on classical liberalism and the age of enlightenment

To not be a liberal, one would have to adhere to the third position - Which is composed by alternate usually non democratic non capitalist views like Fascism, Communism, Stalinism, Right-socialism, technocracy, Leninism, National-socialism, Integralism, authoritarianism, Platonism, etc etc. - Basically anything that is not based on the ideas post-1748.

I'm always amused by Americans saying liberals want big government and are socialists when socialists despise liberalism because it is the cause of capitalism, which socialists must be against - Not to mention liberals don't support workers owning the means of production

Republicans in America are liberals with socially conservative viewpoints, but their basic ideology stems from classic liberalism. this may be hard for some americans to understand because liberalism is all america has ever known - No fascism, communism and integralist regimes.

Ultimately all western and many non western societies are organized according to liberalism and liberal governments (with the meaning I just described) - I dunno if liberalism will last forever, but I doubt that things will not change in 100-500 years. We lived before 1748 without liberalism, and now we are happy with it, but eventually new problems will arise and we will progress as a species, some things about liberalism will have to be reformed.
