Well I guess we should let our entire species slip into dysgenic hell because Hitler.
I'm happy to be in such auspicious company as Winston Churchill, Margaret Sanger, Marie Stopes, H. G. Wells, Theodore Roosevelt, George Bernard Shaw, John Maynard Keynes, John Harvey Kellogg, Linus Pauling and Sidney Webb.
I'm also happy to share a lot of views on demographic trends with the founding fathers, for that matter.
The reason they supported it is because, long term... the only alternative is the fall of civilization. Really.
Just a matter of time.
So I have no shame sharing a view with those people. As for a scenario where I was deemed unfit? Well, based on my personal health, lack of disease history, lack of deformity, and my IQ - it would need to be a very, very stringent standard for that determination to be made about me. If it were, though, that would mean that the species stood to be improved even more than what I was thinking of. So, I'd take one for the team and accept my sterilization.
