The video posted on the Canary Mission website makes it crystal clear that their goal is to prevent "radicals" from getting jobs once they have graduated from college or graduate school. After showing a few clips of people at anti-Israel demonstrations shouting horrible antisemitic slogans (e.g., one young woman is shouting "Go back to the ovens"), the narrator says:
A few years later these individuals are applying for jobs within your company. There's no record of their membership of radical organizations. No one remembers their yelling profanities on campus or attending Jew-hating conferences and anti-American rallies.All evidence has been eradicated and soon they will be part of your team.This campaign assumes that if an employer does not like someone's politics, he or she is perfectly justified in not hiring that person. This may be legal (I don't know if discriminating against people on the basis of their political beliefs or activism is covered by anti-discrimination laws anywhere), but unless it can be proven that a person's politics would prevent him or her from doing a good job, it seems blatantly anti-democratic to me.
