Dangerous is the view that allows us to consider life as lesser, simply based on age. Fetuses will progress down the natural life stages to become full grown humans, that is without a doubt, and you cannot argue that it is not such. That being said, how can you convince yourself, let alone me, that such a being, that is by definition human, is not human, that is subhuman? This line of thinking leads me to one potential end, and this would be an inevitable one as well. Since I have a highly superior intelligence, as told to me by my school after taking tests, then those with lesser intelligences, are therefore lesser in inherent value as well. Which of course means they are substandard. If I consider them different than me, then those that I do consider the same as me, namely those that have a similarly high intelligence, are having resources taken away from us. As this now becomes an Us Vs Them situation, my rational thinking realizes that we need to limit the resources available to these 'undesirables', perhaps even exterminate them. Now I have come to the logical conclusion that since they are not the same as me, and can't articulate, rationalize, or overall have the same thought processes as me, they should be extinguished. Do you not see how this idea is not inherently dangerous? If we are allowed to classify a human being as inferior and subhuman by one trait that they have, then it will be used in other, unforseeable ways, that are in fact to our detriment. I could give many notable examples of this in history, but I doubt you will be swayed by logic or reasoning.?
