I'm not really following what your point is. The context in this case is pretty clearly geared towards connecting people across age generations. In that context, I merely observed that doing that for women would also be interesting. I don't see why you're branching off into random stuff like dogs.
I am equally interested in whether other non-Japanese cultures could do this too, although I suppose its popularity might not generalize across cultures. I don't know. Be interesting to try though, right?
Or is merely suggesting that deserving of some sort of criticism? The whole thing just made me think "why not share a neat thing with other groups". Dunno why that's such a big deal.
