Lots of people are in favor of attractive breasts.
Women are proud of them – or envious of them. Men (generally) want to touch them.
But the fact is that real-world breasts have real-world flaws.
Very few anime shows present realistically flawed breasts. One notable exception is Hozuki no Reitetsu.
I admire that show because it manages to keep viewers interested without ero-moe fan service. It provides a few cute animals and a few elegant pretty ladies who don’t show a lot of skin.
But I am not trying to move you to despair.
I’m just being somewhat smug.
