Who defines what a terrorist is? How can we ensure the GOP, and any future leaders, won't use this against people with differing views? This is meant to be an emotional, irrational dog whistle for people who play into GOP fear tactics. It's ridiculous. We don't revoke the citizenship of serial killers, rapists, white collar criminals (who wiped out the savings of thousands), and GOP politicians who legislate the death of thousands more with their anti-science policies. Why would we do this? As the GOP love to say, there are already laws on the books to hold people accountable. This, as many things the Republicans want to do, reeks of propaganda.
