On Friday, BloodPlusApp put out a request on Twitter asking for blood donations.
What was shocking was that it was sought donors only from the Kamma caste. The Kamma caste is a higher caste found largely in the southern Indian states of Andhra Pradesh, Tamil Nadu and Karnataka.
This is what they tweeted:
#Hyderabad ONLY Kamma Caste Donors, O+ ve blood needed at Max Cure Hospital. 3 yr old CHILD. Pls call 8063266677. Aug 19. Via ShekarNews

The same request was also tweeted by Blood Donors India but it was quickly deleted after widespread outrage.

They later offered this apology:
We are sorry if you were offended by an earlier tweet. We want to help others and are repeating info we get. We will now take greater care.

Quite expected, this shocking tweet reeking of casteism caused an outrage on Twitter with people visibly upset about this blatant casteism.

@bloodplusapp Anyone who says casteism barely exists should see this. Is there something special in Kamma blood?
