I presume you are American. Outside of the United States, left and liberal does not usually mean the same thing, except for Americans who are orthodox left/socialists who could make distinctions. OP and the post are coming from orthodox left criticism of liberalism. He is not making any conflation.

I see you responded to other comments also making similar explanations to you. But it seems that you won't just let up despite being corrected and acting snarky. You got a lot to learn not just the broad historical development of political philosophies.
