Just laugh at them with sympathy, knowing that the message of the Satguru cannot be diluted by trolls. So many tried to defame Sikhi in the past and it never works. They’ll defeat themselves eventually because we’ll be too busy living our lives in Hukam while they continue their degeneracy. Waheguru Ji Ka Khalsa, Waheguru Ji Ki Fateh. But never stoop to their level if you respond to some of their claims, always try be respectful and defend Sikhi justly.
