Spending more time doing X is correlated with spending more time talking about X?

Spending more time talking about X is correlated with spending more time arguing about X?

Spending more time arguing is correlated with higher relationship conflict?

All completely obvious results, strung together with logical fallacies to conclude that video games are correlated with relationship conflict. Although I do have to give the article credit for not implying causation—wait, they do, never mind.

For example, I can assure you that: 1) men who cook more also talk about cooking more, 2) men who talk about cooking more (all other things, including amount talked about in other areas, equal) argue about cooking more, and 3) men who argue about cooking more (all other things, including levels of argument in other areas, equal) exhibit more physical aggression towards their partners. Using the exact same logic, I can conclude that cooking causes relationship abuse.

Do women who cook talk about cooking more? Do women argue about it more? Why is it different for one sex than the other?

To play devil's advocate, women who play video games may be more likely to be with boys who play video games, or otherwise have a partner that can identify with having a time consuming and less than social hobby, one that is also mostly designed to cater to men.
