Yes, words have meanings. What you call "true democracy" is what is usually referred to as direct democracy. You seem to be implying that a representative democracy is not a democracy. It is, it's just a different form than direct democracy.
In your previous post you said that the US is not a democracy, but a constitutional republic. Now you say that the US has a representative democracy, but operates as a constitutional republic, so I'm not sure what you mean anymore? You seem to agree that a constitutional republic can also be a democracy.
To answer your question, I agree with you the US is a democracy. The parent comment did not say that the US is not a democracy, it said that "companies and banks should invest only where democracy thrives". I take that to mean that this user believes that democracy is not currently thriving in the US, which I would agree with.
