I have a set of things that I believe/know (and most normal people believe/know) are simply right or wrong, and I'm not someone who thinks there's any "excuse" for everything (and that all excuses are good excuses). I think there is usually a "root cause" of everything, which is different from an "excuse". So, while I have my black-and-white thinking on some things, I have my gray-area thinking on others.
By the way, this question amounts to a matter of expecting those who answer to do choose the black-and-white answer of either being "one of those black-and-white people" or "one of those gray-area" people - and some people are gray-area enough to be unable to answer a question that asks them to choose a side between the two types of people.
Basically, I think there are a lot of gray areas in life and in thinking and understanding some things, but I think there's also some real out-and-out, black-and-white right and wrong too. My aim is to be a reasonable, understanding, and compassionate person while also having a clear sense of right and wrong. What's black-and-white and what's gray has to be on a case-by-case/circumstance-by-circumstance basis.
