Why is it ok on HN to write "That's funny lol" but not ok to write "That's funny :emoji-for-laugh:". Sure I get that no offense is intended but if twice as many women prefer the second form over the first then HN is unintentionally preferring male communication over female communication. It's not like it would be hard for HN to enable support. In fact they're intentionally disallowing it. I'm sure they have their reasons. I'm just pointing out that the results happen to affect women more than men
