Could I weigh in with some questions?

I don't trust people to accurately describe the difference between something physiologic and pathologic

@Chump_or_Champ sure

my bad. Got distracted at work. lol

Lol

Same

A few decades ago, wasn't homosexuality viewed as a mental disorder?

yes

If so, why? and why has that changed now?

Well

What is the difference between a mental disorder and a human trait

It seems like, at least with the trans and gender bending movement, political persuasion plays a significant role in our scientific and medical research and may have or is perverting our findings and how we proceed as a species.

With the body, you could argue women's cellulite is a disorder, but since about 80% of women get it, it could be described as a secondary sex characteristic

@SpanishAbbey good point. idk.

but cellulite or anything physical has an evolutionary purpose

Again, it comes down to how you make the distinction

Evolution and purpose don't go together

So does homosexuality

Not for the person himself though, more to his sister

Mental things are also evolutionary traits. You can't separate the body and mind so easily

mind or brain? or both?

😛

Both

They follow the same evolutionary pressures as physical traits

I would make that assumption as well.

At what point do we decide something needs to cured?

Who makes that dee

Decision

I dont think homosexuality needs to be "cured" btw, just to make that clear lol

BTW: homosexuality in China wasn't viewed as something horrendous up until the 18th century

Or 19

I have more webbing between my fingers than most. At what point do I need to cure that

Or negative in general

So this highlights my concern (or maybe curiosity) about this issue.

Is how we categorize mental disorders, diseases, abnormalities, etc. socially determined and defined or scientifically?

or are those two categorizations not mutually exclusive?

A lot of basic human traits have been incorrectly made pathological

i.e. California no longer mandating divulging your HIV to a sexual partner (if I'm referencing that properly) in order to reduce the stigma associated with having HIV...

I don't think they are mutually exclusive

HIV is a horrible virus

In relation to extra hand-webbing: I'd say that when something impedes normal functions is the line you could draw. If they don't negatively impact your manual dexterity it's nothing to worry about. But if they do, it's something to be concerned of.
Though perhaps by this same logic, since homosexuality doesn't produce offspring and is therefore a dead end, it would be classified as a disorder of some sort.
