I'm as 'bleeding heart' as they come, and think the flag is fine. It's history, just like the tv show. I loved that show too. I would use it as a teachable moment when kids are around.
Just like when there is a comment somewhere that says, "what's the problem with the flag?" I show it to my kids and say, 'be glad there are dumb people, because without 'dumb' in the dictionary there wouldn't be 'smart'. And my kids are smart, and lucky to be so.
