Well I looked through the resources provided. Perhaps it will take more time to digest.
I can accept a subculture. I have been member of a few sub- and countercultures myself.
But... identifying as other than human? This is still ludicrous to me. Identifying with a particular group of humans I understand. Identifying oneself as being part of a fictional race I do not.
I do not think it is "crazy," just stupid. I am sorry if this offends you. Alienation from larger cultures, groups, society/civilization at large is common, and I don't trust people who don't feel alienated to some extent. The way to deal with it in a positive progressive way, on the other hand, I feel is certainly opposed to the identification with a fundamentally separate group (species). Isolating oneself mentally from the larger group yet continuing to participate in it will have the same effect that a country's isolationism has on foreign wars that affect its own economy. Ignorance of something will not change its influence. Or so I see it.
If it makes you happy, I suppose, I am no one to object. It just seems counterproductive and frankly somewhat childish. To me.
I will keep the option of coming around open, but I cannot lie to myself about what I think and how I feel on the matter.
