Someone provides information.
The reader can then:
1) Take that information, consider it, then either learn to adjust for it to better their lives or discard it
OR
2) Submit a diatribe against men, and the ubiquitous evil patriarchy (in the magazines the reader *chooses* to purchase) that forces the insult of offering what potential partners might find appealing
I would respectfully submit that the further from 20 years old one gets (especially single), the more likely to opt for #2.
