It depends on how 'the gay stuff' affected their society and to what extent. I'm no expert but I am under the impression that it was largely within the context of male dominance and masculinity, not so much the 'effeminate' idea of gay. I also don't think it was seen as a substitute for marriage and family. Something becomes a weakening force I would say, when some basic things like family and masculinity are undermined. Obviously a complex subject though. By 'in the Darwinian sense' I was making the analogy in terms of survival of the fittest. As in, a weakening effect on any entity can jeopardize its long term survivability / viability.
