Life is about reproduction, yes. Nearly every non life-sustaining activity is about sex, and that's not even a thesis, that's an axiom. But very specifically: Furry conventions are about sex. The drunken orgy room parties are far better attended (And yes, I have seen hotel contracts that prove this) than the "main event". Nerd conventions are about sex. SCA events are about sex. They are not exclusively, but as social activities, one of their significant motivating factors is mate-shopping, and there is every indicator that the other advantages of social activity (collaboration and trust building, trading, etc) are not significant motivating factors. People don't get jobs from BDSM conventions (Actually, they do, and then those workplaces go under because hiring people because you're fucking them is dumb).
