GREENPOINT, BROOKLYN — A Brooklyn pizzeria has a message for Americans separating families at the Mexican border: Have a heart.

Vinnie's Pizzeria, a two-store institution that has been serving up slices in Brooklyn since 1960, will sell heart-decorated pizza all day Thursday and send the money to charities helping separated families on the border, owners announced. "Help us to fight the good fight and spread kindness and compassion all while enjoying delicious pizza," Vinnie's announced on Instagram. "The proceeds will be donated to charity organizations currently dealing with the cruel and inhumane separation of children from their parents."

Vinnie's Instagram followers were quick to show their support, even before the shops opened Thursday morning.

"Love this and wish I was closer to Brooklyn so I could order all the pizza!!!" emilyconklin wrote. "Thank you for what you are doing."

"This post is everything right now," added abbadabba911. Vinnie's concluded its message with some hashtags.
