They can in theory, yes. In reality, people focus.

Wait. I have a feeling that didn’t make sense somehow.
It was intentional, just as your misreading of what I wrote is intentional. 
Not surprising, since you’ve been banging this drum for about two years now. I don’t think the left are hypocrites on this issue: they’re against indefinite detentions at Gitmo. A larger chunk of the public, however, decided they thought Gitmo was bad until their Congressmen started scaring them by talking about the detainees as if no prison could hold them. Keeping them in Cuba is fine, but if you put them in jails on the continent, who knows - all hell could break loose somehow. Without broader support, there was no way to get Congress to vote to shut the place down.
In any case your own posts indicate you just want to call people hypocrites on this issue and are struggling to find a reason:
So that makes it hard to take this seriously.
