There's been a lot of buzz in the furry community over the topic of characters that possess attributes of both biological sexes, on one side you have people saying that words like "futa" and "herm" are acceptable whilst "intersex" objectifies real intersex people, and then you have the other side saying that "intersex" is the most respectful term to use and that "futa" and "herm" are slurs.

I think the most neutral term of them all is "gynandromorph", it's a scientific term used to describe an organism that has attributes of both genders. They've even coined a term called "gynandromorphophilia" to describe an attraction to people/characters that have attributes of both sexes, and I feel like this is the word to rule them all, it just feels the most respectful and somehow rolls off the tongue better than "futa" or "herm".

Just my thoughts.

Herm is short for hermaphrodite, which means an organism that has both male and female genitalia. It's a scientific term.
Meanwhile, gynandromorph is specifically an organism that is a chimera of two sets of genes, male and female, that are expressed in different parts of the body. That often manifests bilaterally, like in this bird.

Since the site is primarily using genitalia to categorize genders, I think that "hermaphrodite" is preferable here.
That said, I would not be opposed to aliasing "herm" to "hermaphrodite".

Intersex is any state of having a nonbinary sex. Hermaphrodite is specifically possessing both traits, and Futanari is just the Japanese word for Hermaphrodite. Herm is short for Hermaphrodite, Futa is short for Futanari.

There are going to be assholes who use any possible word offensively; if you try to ditch any word that gets used rudely, you'll have no words to speak or write.

Oh for fuck's sake, no. Hermaphrodite is, quite literally, already the term for a creature features of both biological sexes. Anyone who tries to use it in an offensive matter is an imbecile and should be ignored, not given power to change a completely innocuous scientific term (routed in Greek Mythology) into some form of slur.
