But it was on Reddit that the picture went completely viral.

After Go_Habs_Go31 posted it on social media, on Independence Day, the picture, with the caption "This is what makes America great. Happy 4th of July." got 89,637 points (68% upvoted).

Some people noticed there are a lot of cool shoes in the pic:

While others downplayed the significance of the pics, saying that those sort of things are common in much of America:

A few months ago, native New Yorker Jackie Summers posted a photo on Facebook and Twitter that shows a Jewish Hasidic man and his wife sitting on a New York City subway car next to a Muslim woman in hijab holding a baby.

Caption read: “A Taoist (me) gives up his seat so a Hasidic couple could sit together. They scoot over so a Muslim mother could sit and nurse her baby, on Easter Sunday. This is my America: people letting people be people.”

The picture also fits pretty well in what Apple CEO Tim Cook tweeted to wish everyone a happy Independence Day.

Cook was referring to this particular quote from former President Franklin D. Roosevelt: "Remember, remember always, that all of us, and you and I especially, are descended from immigrants and revolutionists."
