Comment: Imagine allowing terrorists cancel the I-phone over concerns it could cause cancer.  We would not know the advantages and we could never learn if it is possible to mitigate the disadvantages.  

It is too bad these self-righteous terrorists feel they need to shut down education because of fear.  Possibly they could open their minds, shut their hate speech and participate in learning.

Nah, this is the time of Progressive Terrorists.  We don't need no stink'n Constitution or fairness for all.
