As I've been busy, I haven't had time to play with this thread at all.  From what I've read, it appears that BK21 is advocating that homosexual behavior is a genetic trait, which CANNOT be backed up scientifically, it's part of the Cultural Marxist "tearing down of institutions".  A friend of mine recently tackled this for another blog, and rather than rehash what he wrote in different words, I'll just cut and paste my friend Matt's offering:
One of the arguments offered by those in support of homosexuality is  that homosexuality is an orientation that people are born with and it  has the same moral value as the hair color someone has at birth.  The  implication is that since they are said to be born gay, then it is  normal and morally acceptable.  
The media seems to support this idea,  and it is a common position held to justify the behavior.  But there are  two problems with this position.
First of all, there are a  plethora of studies with conflicting results and conclusions on both  sides of the argument.  Nevertheless, we could quickly consider studies  that deal with identical twins.  If genetics determines sexual  orientation, then it should be manifested when studying twins who share  the exact same genetic information.  However, that isn't the case.   Consider this...
"...If genetic influence were expressed in these data, MZ twins (monozygotic, or "identical")  should have the highest concordance for same-sex erotic preference, and  unrelated and half-siblings the lowest. Table 5 is based on pairs in  which at least one respondent reports a same-sex romantic attraction  (N=527 pairs)...
there is no evidence for strong genetic influence on same-sex preference in this sample. Among MZ twins, 6.7 % are concordant. DZ (dizygotic, or "fraternal") twin pairs are 7.2% concordant. Full-siblings are 5.5 % concordant. 
Clearly, the observed concordance rates do not correspond to degrees of genetic similarity. None of the comparisons between MZ twins and others in table 5 are even remotely significant17. 
If same-sex romantic attraction has a genetic component, it is massively overwhelmed by other factors.  As argued above, it is more likely that any genetic influence, if  present, can only be expressed in specific and circumscribed social  structures."

In  addition, genetic information that supports heterosexual attraction is  more likely to be passed to offspring than would homosexual genetic  information, since homosexual practice does not produce offspring.  It  would seem, as the study states, that homosexuality is not genetically  based.  Therefore, 
homosexuality is a learned behavior and should be  called a preference, not an orientation.
Second,  if being born gay means that homosexuality is morally acceptable  because it is natural to them, then it must also be morally acceptable  for those who are born with a tendency to oppose homosexuality.  It  would mean that "heteros" should not be urged to change their  "orientation," nor should they be ridiculed for opposing homosexuality  -- since they are born that way.  To be consistent, the homosexual  community should support homophobia as a natural sexual orientation that  they are born with.  After all, it would seem more likely that  heterosexuality is genetically based since heterosexual behavior  produces offspring where homosexual behavior does not.  So, heterosexual  orientation must be genetically natural, should be supported as a  normal behavior, should not be ridiculed, should have civil rights  protection, and be promoted in schools and the media.  And, homosexuals  who accuse heteros of being homophobic should be labeled as  heterphobes.  Otherwise, the obvious double-standard offered by the  homosexual community will once again rear its ugly head.
Furthermore,  to carry the excuse that homosexuality is genetically based to its  logical conclusion, then men born with a natural attraction to young  boys should also be considered as having a legitimate sexual orientation  with its accompanying moral propriety.  Or, are we to say that only  homosexual attraction is genetic and morally good where pedophilia is  not?  If so, why the double standard?  And, to step further into the  abyss, what do we do with those who are born with the tendency to lie,  covet, hate, and steal?  Shouldn't they all be morally acceptable as  well, since that is how we are born?  If not, why not?
The  problem with using genetics as an excuse to justify behavior is that  whatever tendency we might be born with must be considered normal.  This  includes lying, pedophilia, homosexuality, and rape.  But, such a  logical inference will not be acceptable to the pro-homosexual community  because selective statistics and discriminatory reasoning are offered  to justify their behavior.
