>>2 that's a reasonable theory (that homosexuality is a "genetic disease") and it could help with pop. control,
>>4 and as long as it was recessive this theory might work too,
>>1 and if individuals were forced to procreate, or it were passed by the opposite sex (i.e. male homosexuality by females and vice versa) it could still get around.

however, there is a glaring problem with the idea that homosexuality is genetic: most traits are not caused by a single gene, and something as complex as sexual attraction would be linked to a host of different genes. there have been many studies done to study genetic similarities between homosexuals, and they have found no real correlation between more than a handful of individuals. also, they have tested sets of identical twins, one homosexual and one heterosexual and there has not been any credible differentiation between their genes.

basically, if homosexuality was genetic, it would have been proved by now. some people might still say that "you're just born with it." but if they can't find any evidence... it is definitely a psychological disorder. the only reason all psychologists don't agree about this is because they are trying to be politically correct.
