Holocaust does not defend the fact that Israel is a settler state. As an Indian from the erstwhile province of Madras, we have faced artificial famines and genocide from the British colonizers. High-level British officers and politicians who did injustice on Indians were killed brutally by the Indian leftists, including bombing and shootings, and they're still worshiped to this day as heroes.
So, by that standard, it would be hypocritical of me to see Hamas as a terrorist group. Read about Subhash Chandra Bose, Udham Singh, Bhagat Singh and other socialists from India. I see nothing wrong with their goals. Although the socialists failed to liberate India, it set the message out there for the imperialists that this territory of undivided India is not a welcoming place for the settlers.
