I'm not sure you can claim that someone lacks morals or empathy when that person is demonstrating that a sitting Senator is essentially lying to her constituents about what she can do for them. 

Also, notice how the letter re-frames the argument. This is classic bait-and-switch. Mr. Jared's claim was that healthcare is not a right. His evidence was that it doesn't exist in the constitution of the state or the country. The claim of the 'rebuttal' by Ms. Bentz is that he doesn't believe it's a 'basic necessity' (a phrase which includes things like food, water, etc.). Would she argue that owning a gun is a 'basic necessity'? Because that IS a right enumerated in our constitution. Mr. Jared and Ms. Bentz are arguing two very different things. It is important to understand what the meaning of a 'right' is (especially in the negative right sense of the word).
