> it isn't mentioned at all in the headline that this is a biased opinion piece.

Claims of bias simply for expressing a point of view in an opinion piece are amusing.

How many opinion pieces have you found which in your view do not advocate for a point of view, i.e. biased?

Again, you're missing the point. Most publications (newspapers etc. that also publish hard news) indicate that it is an opinion right in the title of the article so that there is no mistaking it.

The point is that it isn't clearly labeled as an opinion piece. Not that opinion pieces can't be biased.
