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.
I know you're trolling at this point but I will bite.
I'm convinced you were dropped on your head when you were little to be so obtuse. Or perhaps too American to understand anything outside of their own bubble? How do I know you're American? You even censor yourself.
