A lot of them might still be here, they just might not be Hispanics.

Well it seems to me that if somehow one could go back and see to it that your great grandfather didn't show up.....you ain't gonna be you.....there will certainly be some required dna that makes you you missing, eh?

As to their being of partial indian stock....if the conquitadores hadn't showed up, how do they know their ancestors wouldn't have gotten themselves eaten by the Aztecs or the Incas? Or the Carib for that matter?

I think Clombus catches a lot of flak for things he had no control over. It wasn't his fault that the indians were still living in the stone age in 1492. It wasn't his fault that they had no resistance to European diseases. It wasn't Colombus that handed out royal commissions to people like Cortez.
