Well for me to sell my kidney would be out of the question since I have had kidney problems off and on all my life. For the homeless I would be concerned if they had used drugs or alcohol and thus damaged their kidneys. I see your reasoning though in some aspects and there is a demand probably for those needing transplants but on the other hand in my personal opinion God gave us one body and set of organs so why should I sell something of mine I may need to someone who misused or abused theirs. You are right though in one aspect it is YOUR body and if a woman can choose to abort her unborn child because it is her body then someone else should if they so choose have the right to sell their kidney or do what they want with their own body. Otherwise they need to overturn Roe vs Wade because it is a double standard for our govenment to say one aspect of our society primarly woman have the right to choose and no one else does. The government is supposed be of, by and for the people not the other way around. So it should NOT be against the law for someone to sell a body part if they want to any more than it is no longer against the law for a woman to have an unborn human life cut out of her body because it is inconvienient for her or an embarrassment or shame. We should all have the right to do as we want with our bodies be it sell a kidney, pollute it with drugs and alchohol or abort a child right? Of course right otherwise women should have no more rights than everyone else because that violates the equal rights amendment of our constitution and bill of rights which some are stating no longer apply to us we the people today but only applied to those long ago fore fathers who wrote the constitution and the bill of rights. Why not just tell England to reclaim us?
