blood banks which they never "give to" but will "use" to their own means
Striking analogy, Sunspot. The conceited arrogance and blatant double standards are so in our faces that we often fail to recognize them for what they really are.
Likewise, I have indeed never heard any explanation for this moral distortion you mention here.
I could never understand how you weren't allowed to store up your own blood because it had to be spilled out on the earth. Your own blood didn't constitute any of the health risks they were always touting about either. Yet you were allowed to use 99% of the fractions from somebody else's blood bank donation. No blood needed to spilled there...
