The problem is you chose to group your coworkers by gender in the first place, and then assign some trait to that group.

Your comments just end up reaffirming confirmation bias. It also reveals your own bias to automatically associate traits with a certain gender.

Why not group people by color of their eyes, handedness, tallness, and so on? I'm sure if you look at the coworkers with "good communication" you could find common traits that are not related to their gender. So why imply gender as the cause?

Anyways, I think it's something to be avoided and be aware of in your communication. I assume you didn't do it on purpose.
