The 30-year-old actor recently shared Kareena's photo on Twitter, where she could be seen holding a placard demanding justice for the minor girl, whose gangrape-murder in Jammu and Kashmir's Kathua district shocked the entire country.
A user criticised Kareena for marrying into a Muslim family and naming her son, Taimur.
"She should be ashamed of the fact that despite being a Hindu (she) is married to a Muslim. Has a child with him and named him Taimur, after a brutal Islamic barbarian (sic)" the person wrote in reply to the actor's tweet.
Swara slammed the Twitter user for spreading hate.
"You should be ashamed you exist. That God gave you a brain which you chose to fill with hate and a mouth you chose to spew filth from.
"You are a shame on India and Hindus. That s**ts like you feel emboldened to talk this crap publicly is this government's legacy," she wrote back.
Kareena and Saif were relentlessly trolled on social media shortly after the birth of their firstborn in December 2016 when they named the baby boy, 'Taimur'.
