I certainly don't support the death penalty
You stated: "I voted yes ... Slavery was a horrible crime against humanity." So you support the death penalty for crimes against humanity.
I certainly don't support the death penalty, only for terrorists like al-Qaeda or Tim McVeigh.
This sentence is a contradiction. If you wanted to say something coherent, perhaps try "I only support the death penalty for terrorists," not "I don't support the death penalty, except I do."
It was a historical what if question, its not like it has any relevance to today's society.
That does not change the fact that you support the death penalty.
Don't take my response as an insult to your southern heritage.
This is irrelevant and a personal attack.
