Humper, I know exactly what you mean and it's a very interesting question; one I hadn't anticipated with all the uproar going on now. All I can say is that, even though I don't build cars, I'm thinking of going out and buying the "General Lee" kit before they get pulled from the shelves for any reason.
Pawel, I'm not sure how much U.S. news filters to the Polish region but Humper is talking about the recent events revolving around racial issues here in the U.S. In many southern states, the Confederate battle flag (also known as the "Stars and Bars") has historical roots. Depending on your view of it, to some it represents a culture in the Southern way of life while to others it represents a racist past which (they say) is being kept alive through its modern day use.
I don't know the EXACT details but I've heard that several localities have already removed the flag from use and I think even several manufacturers of the flag have stated that they will stop producing it. Warner Brothers, an American entertainment company, has announced that it will no longer license the use of the "General Lee" car. The General Lee was the name given to the car in a popular TV show from the early 1980s called "The Dukes of Hazzard". (General Robert E. Lee was the commanding General in charge of all Confederate forces during the American Civil War.) The General Lee had the painting of a giant Confederate flag on the roof of the car and was very prominent and was basically the identifying feature of the car. It actually looked really neat especially painted on the top of an orange American muscle car. If you do an internet search for "The General Lee" or "The Dukes of Hazzard", you'll see what I mean.
Anyway, that's the basic gist of what's going on. I tried to explain things without getting too political. I've always found it fascinating to learn about different cultures from around the world and I hope I've given a little insight of it to you and other members outside the U.S.. What I've described has barely scratched the surface.
