I can't speak for the person you're replying to, but I'm against any No Fly lists, both for the pre-crime aspect and for the the opaqueness with which its implemented. Sex offenders, by definition, have committed a crime. So that's not really a pre-crime list. Although, sure, some people may not belong on those lists, and it's pretty life-ruining for them. Your point reads a bit like this: "These injustices exist that you should be against, so why are you supportive of them?"
