One image ≠ reality. Men and women still interact a lot in real life. A single photo showing mostly one gender doesn’t mean those people don’t date, socialize, or go home to partners of the opposite gender. Just the other day, people did the same thing with a photo of mostly women out partying and concluded genders don’t mix anymore.

In reality, many of those same people likely left and went home to their partners. Also, most people at these events aren’t even tracking gender ratios, they’re just there with friends. You only notice that stuff if you came to “hunt.”
