How do they justify adding a restriction based on nothing? Did they just decide one day, "Hmm, we'd better restrict those genetic freaks from these duties, even though there's no evidence that they're a hazard."
Come on, that's a flagrant disregard for human rights!
I read Dr. Pape's article. In parts, he sounded like he was suggesting some conspiracy against colour defectives. Growing evidence seems to suggest that he's onto something. What? Are we a threat to their genetic integrity? Those of us who've been through those tests no how much they seem care. You can tell they just want to say, "What are you doing here? Get out of my site you vile, impure creature!"
