I live in Boise so I can watch to see what happens.
If this is just taking place down at BSU then it won't really effect me, and pretty much won't effect anyone else except the people that already support the "diversity week" and would be at the event anyways.
Now if this were taking place AT the walmart stores themselves then I would have a problem with it.
Counter-protest? Probably not, but I definitly wouldn't shop at the stores during the week this was taking place and 95% of my daily shopping is done at Walmart, the other 5% at WinCo (WinCo has better meats, produce, and deli).
Another thing I thought of though is I believe Walmart in Boise just blanketly sponsors Boise State University. You can buy BSU shirts, hats, even doormats at our local Walmarts. I haven't seen other colleges except in the generic clothing section. BSU gets special bins and such.
I don't think that the local Walmart specifically sponsored this event, but instead sponsors BSU as a whole.
