>>>> Double dilutes suffer from sun sensitivity and an increased risk of skin cancer and vision loss. THAT'S why (sensible) people want to avoid breeding them.
?? Re-read my post. I SAID that some people don't want double dilutes.
Some people like them.
As NRHAreiner said, many colors/patterns have the similar/same sun sensitivity/cancer risks, and the eyesight claim? Not true. Blue eyes in horses aren't more prone to vision loss. Eyes with light skin around them are more prone to cancer of the eye structures due to sun exposure-- as can be applied to some paint patterns, some appaloosas with extensive mottled skin, any bald faced horse w/o eyeliner-- and cremellos/perlinos actually have SOME pigment in their skin as it is not truly pink skin, but light skin, so they are better off than an extensively pink-skinned horse.
ALL of the above can wear fly masks/sun shade masks, and if needed, sheets when outside, so risks are minimized.
(say the "sensible" mom of 2 blue eyed blonde kids which I don't consider inferior due to their genetic potential to sunburn, LOLOLOL-- but I DO have a good supply of sunscreen and hats....)
