Okay, I misread the original claim, my bad.
However, the majority of Texans according to the 2020 census is of latin/hispanic ethnicity (40.2%), followed by 39.8% white.
I don’t know what US americans need to claim any descent or ancestry, but I have a feeling that more people would claim spanish than german.
Spain is Europe, too!
In the end, all of the European colonists played a role in the genocide against native americans. And my remark mostly was just a snarky reminder that it wasn’t uninhabitated land that was settled.
