i respect your stance, really i dosadly the only thing we can do to prevent things like this is by eradicating individuals who carry the genes which are responsible for these things.
Today, with things like plastic surgery and various treatments for recessive/degenerative conditions, people who would normally be selected AGAINST in the evolutionary process and die off are aided to reach reproductive age, reproduce, and further pollute the human gene pool.
It's a tough stance but it's the only rational way to secure a future for humans.
...but who is to say that these people are any less perfect than you or i? ALL of us, and i mean ALL, contain mutated genes. our evolutionary history is there because of mutated genes. physical deformities might have been a disadvantage back on the plains of africa when hunting for impala, but here in this day and age, many times they make for advantages. how many times have you met someone with down syndrome that was rude? who are you to say that the dude with a bum leg should have been eradicated? he might be one of the coolest, smartest dudes around.
ass backwards fundies who cant tell sartre from favre should propagate just because they have perfect skin and beautiful blonde hair and blue eyes? but someone with one too many chromosomes should have been aborted because his eyes might be almond shaped?
