The mermaid 's kiddy , unrealistic version of disney is totally wrong
The mermaids have breasts so they are mammals , so their tail parts are supposed to be smooth skins , like dolphins and dugongs , not scaly like fish tails .
Also , did some of disney cartoons promoted Beastiality ?
The Little Mermaid : Human VS fish .
Beauty and the Beast : Human VS beast .
The Princess and the Frog : Human VS frog .
Zootopia : interracial between animals .
Here is a more realistic , more better love story between a human and a cute , mute mermaid : http://kissmanga.com/Manga/Ryuu-no-Kawaii-Nanatsu-no-Ko/Vol-001-Ch-002--Mermaid-Sanctuary?id=179039
