Because the implication is that without embryonic stem cell research, he looks like that all the time, when in reality he is much closer to "normal" when he takes his meds. The problem we have is not with the symptoms of Parkinsons, its the deception MJF uses both in his appearance and his words in order to push an agenda.
There is no deception in abortion pictures. What you see is what you get, and no amount of medication makes murdered babies look/feel better or worse.
Just because he takes medication, does not mean he's not seriously ill or won't die sooner because of it. There's NOTHING wrong with what he did. The meds he takes to appear more normal, have other side effects that are horrible. I just don't see why it's unfair for him to do this. It's reality...and our side would do it to if it it suited our needs. Just disagree with him, don't attack his illness. THAT is real.
