Is it? Connect the dots. The South was left to rot, Blacks and Whites. The lack of financial support perpetuated racism. It bred resentment. It left tens of millions poorly educated, and it helped put us where we are today.
People looked for positive symbols and heros, and found them. Butt hurt because they lost the war is you perpetuating a stereotype and is a great example of how many today STILL blame great great great grandchildren for the sins of their ancestors. Your righteous indignation might make you feel better, but that attitude is one of the primary reasons millions are still suffering, and they hate you for it.
