And, you miss my point.
This wack-job pledged allegiance to ISIS right before the attack.
I have zero sympathy for idiot terrorists like this, because, obviously, this guy is a terrorist.
Domestic Terrorist? Yes.
Islamic Terrorist? Turns out.
That has little bearing on his status as an American.
When someone as American as you or I (Timothy McVeigh) lost his mind and went full-idiot, no one remarked that he was un-american.
Were his acts un-american? Positively yes.
Does that change the fact that he was American? Positively no.
My larger point was that Trump restricting Muslims from emigrating to the US wouldn't stop attacks like this one, since this idiot was born in the US of A.
And, the FBI surely isn't worried about me bro.
