First, antisocial and unsocial are not the same thing. I’d say pooping is unsocial but not antisocial. It isn’t working against the fabric of society* but it’s just not something that’s done out in public. If you’re asking why we have these rules, and if they’re “good”, I’m the wrong person to ask. I know they exist, I believe they exist because of Victorian scatological taboos, and I think they’re a little silly but hey they’re what I’m used to.
*unless you leave one on your boss’ desk, for example.
