I don't need to label it anything because none of my arguments rely on it being either way. But in the exact same way that a broken arm isn't natural (even though it exists in nature) neither is homosexuality. There is no biological function for it, it exists because a system with a function is broken and exhibits in this way. That is what I call abnormal, dysfunctional, and unnatural. For me it is a descriptor. The problem is that for you it is a category. A grouping. Because the way leftists think is group think. You believe that if you can label something then you have "proven" that the thing you labeled has all the properties of the group you put it in. I realize that is a human nature kind of thing, but humans who overcome that kind of backwards thinking move their politics to the right where things make more sense.
