Should 5-year-old kids allowed to see cartoon series where there are princesses and prince? Should they be exposed to romantic inclinations that are subtly shown?

Awww why would that be a problem? If kids cannot be exposed to romantic inclinations, then how can they be around their loving parents? They should also be banned from reading fairy tales if that's the case. I think it is unrealistic to "protect" kids from such things. Plus, love and romance is wonderful thing. At their age, what they will take away from watching such cartoons is the essence of love, caring for one another and friendship -- all of which are great qualities. They should be protected from mature content and violence not kids shows.
