Sickle cell is genetic and by its very nature can be passed on. Homosexuality in its very nature prevents reproduction, therefore its alleged benefits cannot be traits meant to appear in subsequent offspring , which by the nature of the condition, cannot exist. Its essentially like claiming being born without reproductive organs is meant to help the species. Something that by its very nature hinders continuation of the genetic line cannot really be considered biologically positive.

Not that I'm arguing one way or the other, but allow me to point out that sexual behavior falls along a
continuum, like just about any other human (or, if you like, animal) behavior.
There are, after all, bisexuals of both genders. It is not a binary, go-no-go phenomenon. This has been demonstrated in many cultures across many ages. So,
if it is "genetic," there is no "need" for it to be automatically bred out. The genes, if any, can be carried forth by bisexuals --and in some cases, they might combine in the offspring to generate a totally homosexual individual. Or, on the other hand, the offspring may be totally heterosexual and carry the genes (again, "if any") forward to succeeding generations.
But in the long run, across large numbers of population, there is no need for the "genes," (again I emphasize, if any) to be weeded out because of any supposed nonreproductive behavior.
Just wanted to point out that homo- versus hetero- sexuality is not necessarily a binary phenomenon, and that homosexual behavior would not necessarily be eliminated merely because "homosexuals don't breed."
They can, and they do.
Fortunately for the species, almost no characteristic is that binary in nature, as Firethorn touched on by his use of the term "complex of genes."
We, after all, still have babies crop up with six toes now and again.
