Because they were terrorists, we didn't hold 3 million of them in gitmo simply because they were ethnic minorities.
Orders of magnitudes in difference.
Holding a few dozen suspected terrorists !== holding 3 million people (nearly an entire race)
You can justify there may be proof for those few alleged jihads. You cannot reasonably prove those 3 million people are all terrorists.
Where are the cries to shut down these camps like there were cries to shut down Gitmo?
