I fail to see why, linguistically, "homosexual" can be considered a barbarism in the same way that "homophobia" undoubtedly is.

"homosexual" means attracted to the same sex, whether male or female.
Is there any other succinct way of describing the condition?

It should also be noted that "homo" meaning "man" in Latin has no connection whatsoever with "homo" meaning "same" in Greek.
