One woman wrote: "I am Muslim and I love Christmas".
Some have taken to Twitter to express their disapproval of the advertisement, noting that Muslims do not celebrate Christmas.
Some racist viewers had complained because the advert features a Muslim family greeting each other with gifts ahead of the big day.
Tesco's seemingly innocuous Christmas advert has sparked a backlash and a subsequent heated debate due to its depiction of non-Christian families celebrating Christmas. It is the celebration of the birth of The Christ.
"We want our customers to know that however they choose to do Christmas, and no matter what they need, we can help - Everyone's Welcome at Tesco".
"One fumed: "@Tesco just seen your Xmas advert - you don't have a turkey for me, I'm vegetarian".
Shoppers are threatening to boycott Tesco after its latest Christmas advert.
"The supermarket added that the Christmas campaign "will celebrate the many ways we come together at Christmas, and how food sits at the heart of it all".
Another wrote: "How dare you feature a Muslim family in your CHRISTMAS advert!"
Tesco has previously been threatened with boycotts after it was suspected of selling unlabeled halal meat.
At the launch of Tesco's festive campaign, the supermarket's chief customer officer Alessandra Bellini said the ad was meant to "celebrate the many ways we come together at Christmas, and how food sits at the heart of it all". The supermarket chain explained that some of its meat products are processed to halal standards, but the company does not specify to its suppliers that halal practices should be followed.
