Yes. I believe he sees himself as other than Irish and has used his citizenship entirely disingenuously and as a flag of convenience. He knowingly broke the laws of the state that arrested him, at least as they see it. He and his family are members of a dangerous and extremist organisation but his sisters stand in front of cameras and pretend that none of this is true.
The people that shot the staff of Charlie Hebdo were born in France but don’t see themselves as French. The nationality argument is totally spurious in many cases. The do-gooders make me want to puke. They are typically misinformed. Yet if you disagree with them, you are by definition racist or angry or whatever.
