When I was a kid, I grew up in a small town (less than 5000 people) in the South-East. The town still had businesses that didn't... uh.... "cater" to specific crowds based on skin color. Though I am very white, my family didn't abide by bigotry or hate of any kind (my grandparents on my mother's side escaped to the US during the early 40's from Nazi Germany). So I gathered up as many people as I could of as many colors as I could and we grouped up in front of the 3 stores that didn't "cater" to "other" crowds. We made sure not to block business, but we also made it painfully aware the reason we were standing there in front of those stores. We didn't actually change anything at that point, but 2 years later all three of those businesses were out of business. I would like to think that we helped move the town forward.
