Sad to say, that slogan is crap - will you be okay with that poster on a suicide bombers wall, or gun mental addict who thinks his ideology is sacrifice everything, including death. Come on. Nike will get some people, and will lose a lot also with this type of slogan. They took a guy who refuses to stand up for the flag of America, when he was at work, and made it ok. Not cool.
BUT
That is Nike's choice to do, the same that it is other people's choice to choose WHAT shoe to wear. I don't want to nor choose to tell anyone what they can or cannot say during their own time.
For me, for this week or month, it means that I will NOT be buying any Nike shoes right now, and look for another brand, which as a consumer, I can do.
