This is an ad hominen if I ever saw one. You basically disliked the message and felt entitled to condemn the author's personality as immature and used that as the basis to dismiss their opinion as a misunderstanding.
The fact that a big chunk of romantic partnerships and friendships start in the workplace among co-workers tells me a quick cynical dismissal of co-workers as a shallow and single dimensional relationship is not very insightful.
Conversely viewing your coworkers as a massive extended dating pool suggests to me a level of social desperation that's hardly worthy of discussion much less serious consideration. That relationships form at work isn't in question, that's not the point of the exercise however.
