The homosexual movement strikes at the bedrock of one of our most stabilizing institutions: the procreative family. In doing so, it unpins the collective values of a society, which in turn devalues the traditional and equates it to the merely novel. Having done that, the next step is to impose a capricious -- rather than natural -- "order" upon the ensuing chaos. Of course, that order takes all its cues from Marx.
In short, this is Hegel's dialectic at work.
