I know I'm getting repetitive, but again, the rabbit horde is irrelevant.
Of course humans are in a different social group by default. That's normal. But so is any given human being part of at least a few social groups. If your claim is that you refuse to consider yourself part of ANY social group, I flat out don't believe you. Humans that don't have any social backdrop for their lives are universally either suicidal or they're sociopaths.
The fact that you believe that the population could do well by reducing it's own numbers is intriguing, but unless you're willing to stand up for your beliefs and act on them by doing some culling yourself, it's merely a psychological game and -- again -- completely irrelevant.
I often get asked that.
But, if I was to take a gun with infinite ammunition and shoot a chinese man (nothing particular against chinese, just an example of a mass population base) every second I would still have not killed enough men, to even stop the growth of the country.
In fact more people die from starvation in that country than I could possibly kill in my lifetime with conventional arms.
Such is that I do not have the resources to make a difference. If I did have a method I would likely use it without question if it could guarantee erasure of humanity. I would not expect you to understand, you likely are not a Misanthrope as I am or have the same measure of practicality as I do.
Lets add to this.
Do you do something if you think it is Immoral?
I am of the belief that any action can only ever be correct at the time of the action. Only afterwards when the results are seen can I decide that my action was not correct because of the light of new evidence but I could not have made a more correct descision at the time.
So if living a life of comparitive luxury when people in a far away nation starve is immoral to you, do you take action to try and solve their starvation? If not and you ignore the situation its not something Immoral now is it?
