My NAY is not based on a belief that joining a terrorist group is not a horrible thing. It is based on my distrust of the system that would define which groups are terrorists. What would prevent Ted Cruz from defining a non-Protestant non-Pentecostal group as terrorists against his Christian sect? This is a dangerous precedent--not unlike the Patriot Act which created a mass surveillance state! I imagine that a person who joins a terrorist group can be charged with a number of illegal acts & this is unnecessary except in the the punitive world of right wing zealots who would happily incarcerate 90% of the US population if they could get any with it!
