DETROIT — A Thanksgiving ad by Best Buy that wished readers a Happy Eid has upset some critics but pleased American Muslims.

Eid al-Adha, a Muslim holiday, happened to fall this year on Black Friday.

In the ad, Best Buy says to “Shop Thanksgiving Day at BestBuy.com,” according to a copy posted on Crunch Gear. Right above in smaller print, it says, “Happy Eid al-Adha.”

Some conservative blogs are angry over the ad, with a few calling for a boycott of the electronics retailer.

Muslim-Americans welcomed the ad, seeing it as a sign they are increasingly part of the American fabric.
