If I may inject a counterpoint,
Now, I am not saying I support commercializing holidays or making people work them. Having worked one of those jobs where you have to be there during the holidays though, protesting it by not shopping actually screws the employees over. Companies expect to hit a certain dollar amount during holiday sales. If they don't make that money through business, they'll make up for it in other ways, namely cutting hours and letting seasonal help go and leaving the store with a skeleton crew where managers expect the same level of performance from them with 1/3 the man power.
Rather than hosting some kind of civilian embargo, I think people need to write to corporate leadership expressing how disappointed you are that they are keeping people from their families during a holiday that is entirely about family, and also harass your senators and representatives about companies giving these employees better benefits, compensation, and working conditions.
On to the OP, my favorite part of Thanksgiving is the food, but not eating it. As long as I can remember, I have yet to experience one thanksgiving where something didn't go horribly wrong with preparing the food. I remember my dad trying to carve a turkey after its wings came off. It was like watching a grown man try to carve a solid rubber football.
