Probably because that's two different type conflicts. The majority of my family 'fought' for the South. We felt that was a rich man's war, we didn't own slaves, and we really wanted no part of any of it. Didn't matter, they came and got you out of your field and you were now a Confederate soldier. Bring your own equipment. Maybe other folks have a different view of it, and good for them. I see nothing to mark about it. The only way my family 'mark' it I guess, is on Memorial Day. We call this 'Decoration Day' and it originally started as decorating the graves of rebel soldiers killed in battle. Then it went on to putting flowers on the graves of all who had passed on, and got called Memorial Day. These days it appears Memorial Day means 3 day weekend, go to the lake, get drunk and raise hell. I guess all our ancestors would be proud.
