This may be the wrong area for this but here goes.
If you went to a bank and told them " I don't have an account with you, I never will have an account with you and I will tell people you are a terrible bank" then ask not for a loan from them, but a gift of a lot of money, how do you think they would respond?
Yet, witnesses now have the the ability to take blood fractions from the blood bank without ever contributing to the blood bank. There is a process that the blood bank takes just the plasma from a donor to be used for fractions only. If it is acceptable to accept fractions from plasma why is it not acceptable to donate your plasma for fractionalisation? Double standards.
Imagine the hospital saying "before we give you a lifesaving fraction you need to prove that you have contributed to the pool". If you are healthy I reccomend people think about donating to this great cause.
