Let's have a serious, non-fetish fueled discussion on the implications and effects of pokemonXhuman relationships in the pokemon world.

How would this negatively affect human birth rates?

How would it be seen by society? Tolerated, dont-ask-don't-tell or out right illegal?

With what pokemon (be it legal to have a relationship with one in the first place) would it be seen as tolerable and which ones would be taboo (going from human-like ones such as a Delphox and Machoke to inhumane ones like a Cloyster and Dragalge). Would the pokemon species in question's iq be a gauge?
