Yes, there were and are plenty of protestors that actually support Hamas. Fuck those guys. But automatically claiming that if you support Palestine that you must support Hamas is the exact sort of childish intellectual laziness that leads to and supports actual genocide.
I do see in there a reference to Kymani James, so I did a search for him. I see that he posted incendiary comments online which he later recanted and were taken out of context when reported on. But, I don't see how your post indicates a connection to Mahmoud Khalil, and even if there was a connection, why this warrants detention and deportation?
Regardless, the prohibition for entry/approval is against people who were associated with the nazi party or nazi-allied parties between 1933 and 1945, which is basically obsolete already. Anybody for whom that prohibition applies would be 98+ years old now.
And I never said it warrants detention and deportation. I'm just pointing out that Khalil is affiliated with a group that supports Hamas, and that he does not merely "protest for Palestine". It's well attested in the media that Khalil was a negotiator for the group but I can link a source below.

The article that you linked says he was a negotiator for Columbia pro-Palestine protestors. Painting them as supporters of Hamas is a tired tactic intended to silence anyone who doesn't support Israel's actions.
Look up the line on nazis. On second look, The word advocacy is wrong. It is nazi persecution
