If ignorance is believing that the people that committed this despicable crime against a totally innocent man are worthy of me understanding why they did it, then yes I will admit to being ignorant.
Or maybe you are the one who fails to see the Cohen brothers for what they are? Is bullying, violence, harassment etc all acceptable behaviour in your book? Maybe I am in the minority for thinking what they did is inhuman, but judging from the number of people who are pleased that justice has been done, I doubt it.
