I will say that in terms of atrocious statements, I've noticed that conservatives/Republicans tend to be most guilty of factual errors and being insensitive to others' situations, while liberals/Democrats tend to wish bad things upon those who disagree with them.
Interesting idea. Why do you think this is?
I think as IndyTexas demonstrated later in that post, the ill wishes from the liberal side (including the quote in the original post) are intended to force the person to see the need for welfare or affordable healthcare.
