And what defines a terrorist here?
The same as a terrorist (or one that causes terror).
Merriam-Webster said:
: violence or the threat of violence used as a weapon of intimidation or coercion

How do you feel about the idea of this? I'm mainly asking from American citizens.
I would prefer GITMO as it's an American prison, if the act merits. I do not want to see Americans housed outside of our country, despite what they did, as it sets a bad precedent. What if the next regime did the same to their seen political enemies? It's a slippery slope.
In the case of rapists and murderers, that's fine
Not to me. They are Americans who are still protected by the US Constitution, and that could be considered cruel and unusual punishment, unless we let them set the standard that it isn't, which is a slippery slope.
I believe criminals should be punished but this does not mean humans should be treated like animals.
Some (sub)humans do. But, unfortunately, we can't dish out that kind of punishment, especially to our own citizens.
Sending them for life imprisonment is better punishment than killing them
No, extreme SA and murder of a child should be an immediate death sentence, with a focus on a "speedy trial" so that if there is such overwhelming evidence, appeals can't take decades. They do not deserve to live among us, as they stripped that right away from their victims.
I've been seeing some actually Americans have been hit in the cross fire and have had their houses raided.
Perhaps because they're housing illegal foreign terrorists, i.e., TdA and MS-13?
Should they be sent to El salvador? Absolutely not. They're not from there.
If they commit a crime so horrendous that it's worthy of, yes. They are green card holders who are subject to no due process, in the traditional courtroom sense, as it's at the State Department's discretion in these cases.
I wouldn't like to be sent someone that I'm not from nor raised.
Simple solution: Don't commit a crime or be linked to foreign terrorist organizations.
