yes, this is what i am saying. modern liberalism is indeed a "core ideology", or put another way, a hegemonic centrist ideal. it is definitionally not leftist. i think it is well understood that most leftist political ideologies recognize the importance of a liberal movement as a precursor. to the original comment this stems from, leftism is in no way an endorsement of consumerism.

I find it more useful to use more "absolute" terms. If by left you mean some fashion of socialism, then indeed left is not liberalist. But in contemporary politics such left is almost non-existant. E.g. most European "socialist" or even "communist" parties are staunchly liberal, and mostly celebrate consumerism.

I don't think "leftism" is really an ideology, or at least it can mean very different things in different contexts.

Edit: I find it also better to use "liberalist" instead of "liberal" when referring to the political movement and ideology. "Liberal" is easy to misinterpret and misuse, and it tends to hide the fact that liberalism a quite specific ideology, that e.g. has no monopoly on liberty.

Especially so called radical liberalism was very important for development of various forms of leftism such as anarchism.
