garysher;

Why on earth do you assume that evolution has "no purpose, no needs, no plan or desired outcome".

Nothing could be further from the truth.

so you are a creationist.

Of course there is a reason why fish evolved to survive underwater, crocodiles have eyes on the from of their heads (sic), and giraffes have long necks.

you are mixing your arguments. there are reasons why fish live underwater, and benefits to a giraffes neck. but there was no reason why giraffes evolved long necks in the first place. they could have just as easily evolved in a different way. if they had, would that have defied their purpose ?

Every single organism on the planet has evolved for a purpose - there are no exceptions.

every organism has evolved. every organism has evolved structures and instincts that aid its survival and aid the propagation of its genes. but there was no guiding hand in this process. it is a blind process. evolution had no "purpose" in mind when producing any organism, including us.

But behavioural abnormalities such as homosexuality are not a result of evolution, by definition.

this might be an interesting start to a conversation about evolutionary science, but lets keep it focussed. you are assuming from the beginning that homosexuality IS a behavioural abnormality. lots of variants in nature are beneficial, whether physical or behavioural.

They are a result of a physical and/or mental defect. Just like blindness, dwarfism, siamese twins and the clinically depressed. None of these serve any purpose either.

And based on your continued refusal to provide any evidence to the contrary, one can only assume you agree, but are too stubborn to admit it.

you have a habit of assuming too much, but i dont think i will be able to stop you there. i have a habit of assuming things about you too, so i cannot complain.

i do not think i have failed to provide evidence. i may have failed to provide evidence you find accessable, or understandable, or believeable. i hav certainly provided more independent information than anyone else. there have been those who disagree with what i am saying, but they have admitted they have not read most of it and oppose it on the basis of their opinion only.
