Seems factual

Pre-contact, tribes like the Comanche and Iroquois built empires through brutal warfare, raiding, and displacement, often with ritualized torture or scalping as cultural norms. The Apache, for instance, terrorized rivals long before Europeans showed up. Europeans, though, brought industrialized violence—guns, steel, and disease—plus a mindset of total conquest, like Cortés toppling the Aztecs or the English massacring the Pequot in 1637. Native violence was often localized and tribal; European violence was systematic and scalable. Data’s sparse, but archaeological evidence of mass graves (e.g., Crow Creek, 1325) shows Native bloodshed rivaled Europe’s feudal wars. Both were violent—Europeans just had better tech and bigger ambitions.

The english committed the greatest genocide known to date in America. Hitler couldn't even come close to them.

Open a history book. It was the Spanish that brought the diseases that killed 80% of the natives, not the English. When the Jamestown folks arrived they found many empty villages.

History is different depending on who tells it. Today's most honest versions of events are different from what was told 100 years ago.

Both the Spanish and the English committed abuses of many kinds.

The English were worse, clearing the area of ​​indigenous people, deceiving the natives with false peace agreements, and systematically committing genocide before their independence from the English empire.

Meanwhile, the Spanish were the opposite, committing some acts of genocide after they became independent from the Spanish empire. The Creoles committed genocide.

By that time, most natives had already genetically mixed with the Spanish, which is why Spanish-speaking countries have massive indigenous traits.
