No. Cancer is a disease. But I can see how you could believe that.
A disease that fits your "genetically human, and distinct" criteria. That is the point. Your criteria for individual personhood is insufficient. No organism that requires a host to survive is "individual"; it is, at worst, parasitic; at best, symbiotic. Either way, it is
not an individual, and the only
person whose rights, and choices matter is the woman's.
In my opinion. Now, please understand, I do not
require you to agree with my opinion, nor to act as if you do. However, I
do require that you do
not try to force anyone else to behave as if they agree with
your opinion. That's all.
You believe that a fetus is a completely individual life, and is ,at least,
as important, as the pregnant woman, if not more important. Okay. Then, by all means, never have an abortion. And if anyone ever tries to pass a law to force you to, you can count on my support to fight that law right along side you.
However, not everyone shares your opinion. So, please do us the courtesy of not trying to force everyone to behave as if they do, by force of law. That's all we ask. We're not asking you to agree with us. Just stop trying to pass laws to try and force us to behave as if we agree with you.
