> Are we not allowed to discuss the title of submissions, only the body of text?

You're certainly allowed to do anything you wish for, just as you're allowed to discuss novels based solely on their title. However you seem quite offended, is that some sort of meta-acting demonstrating your original thesis through the medium of yourself?

Nevertheless, if you're discussing the title and ignoring the body, you're quite literally missing the forest for the tree, or in this case missing the forest for a signpost. This article is not a Cosmo listicle, its title is neither its meat nor its thesis, it's a starting point.

This is very often a bad idea as titles are often not written by the articles' authors, and are often written to generate clicks rather than to accurately summarize the article. IMO it's to be discouraged.

Edit: It's kind of like discussing the layout of the site. There are occasions when it's reasonable to do so, but generally people want to discuss the content.

Agree. I didn't like the article. I wish i haven't read it, really it it was waste of time. Sorry author, don't get offended, please.
