I know it's warm and emotionally appealing to want to, "sympathize," with others, but this trite, threadbare adage is always applied in only one direction. Why is the streetbum never asked to walk in the shoes of the successful businessman, who employees others, and has put everything he has on the line to produce goods and services others desire?
You probably have one of those bumperstickers that read, "Mean People Suck." You are against people who have values and choose to live their lives in accordance with them and allow their values to govern the way they interact with other people. Yet, in your animosity towards them, you are embracing the ultimate hypocracy.
I would die for your right to disagree with me on any issue. Just don't expect me to agree with you.
