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.
That doesn't make it any less mean-spirited. I guess conservatives could do it too, but I can't think of a scenario where it would work. Let me try these...
"I hope there's a time machine that goes back to before you were born and that your mother has an abortion so you know how painful it is to be aborted!"
"I hope you start a successful business and make a lot of money so you know how difficult it is to pay so much in taxes!"
"I hope your melanin disappears and your genitalia invert so that you can see firsthand how hard it is to be a white male in this country!"
