What about asexuals? and pansexuals?
Is this for me?
If so, I just have to say here that I don't have any hard evidence to back my beliefs which are complex and cross over into more complex subjects like spirituality and the nature of existence. I haven't given this subject too much thought so it's not easy to put anything forward with clout. But I'll give it a go.
All living things have an inherent drive to reproduce (and diversify). Plants, animals and whatnot. This drive has biological manifestations (e.g. gender specific pheromones etc), but it has a non-physical / spiritual / energetic root. This has to be the case to sustain an environment of diversity, change, expansion and creativity (even within groups) - which the earth is intended to be. [As intended by God/Source/Non-physical].
Looking specifically at humans, if you for a moment consider that we are eternal spiritual beings at our core (eternal souls), and so also entertain the idea of reincarnation - you are more open to considering the idea that between lifetimes, decisions and intentions are made at the soul level about what else or what new way of life can be experienced by a given spiritual entity in their next physical form (- ideally an intention that may benefit the expansion of humanity as a whole and allow the soul to expand in terms of knowledge about the countless ways humanhood can be experienced). Past experiences are taken into account (been there, done that). Hence, all souls have experienced being men, being women, being third/fourth gender, being every race, and every ability.
Gosh I hope you've been able to follow this mess of an explanation so far.
Pansexuality and Asexuality may fit into this system by offering new relatively unique vantage points to the human experience. Isn't it just interesting to experience life without the drive to connect sexually (asexual) or without rigid ideas about who you should be connecting with and in what way (pansexual).
I don't think I'm doing a good job explaining, but what I'm trying to say it that, there is a need to heterosexual drives to ensure the survival of the species (which may account for why heterosexuality is the dominant orientation in all living things), but alternative sexualities are not disorders. They are deliberately intended perhaps just for the experience of something other than heterosexuality, but also as a reminder to humanity to not get so bonded to ideas about beingness and the rightness of things. God/Source/Non-physical is a fluid and creative - process/thing.
Diversity is just the order of the day. There's no good reason for different races other than the diversity (as with the different colours of flowers and birds).
Fuck this. I'm sure you guys will dismiss this as baseless mumbo jumbo - but as I said, I haven't focused on this topic in this way, so it's difficult to lay down an argument with real clout. But I think my essential point is that, these topics can be almost impossible to grasp because we leave god/soure/that-which-we-don't-understand out of the equation. It's like trying to answer the question where does water come from, by saying 'the tap'. When in reality, there is a bigger picture available.
