It's an especially good example because it is an opinion piece. It checks facts, cites sources, and presents a lot of evidence instead of just giving a straightforward opinion. All these facts give legitimacy to the implications. Instead of making the article more objective, they enhance the bias.
I never said anything about it not being an opinion piece, just that it's published by the media.
I agree with your original critique, but writing "the New York Times recently wrote an article" is not saying "just that it's published by the media". Whether or not an opinion piece is sufficient to make your point, you said the NYT wrote it, it turns out that they did not, but you are claiming that despite this you were right all along. Don't do that!

It's an opinion piece, so neither is it written by the New York Times, nor is it surprising that the author might be "inserting opinions".
