You know, these people running for the presidency of the United States should inspire confidence they know what they are talking about. People look up to them for leadership and believe what they say. When Rand Paul says he's "heard of many tragic cases of walking, talking, normal children, who wound up with profound mental disorders after vaccines" all people hear is that vaccines give kids mental disorders... and worse yet, some people believe it. . . after all, a presidential candidate is supposed to know something like this is true before saying it.
Unfortunately, once again science and research were thrown out the window in favor of "many" cases he's supposedly "heard of," not that he has first-hand knowledge of, not that he's seen, not that he can provide evidence of, just heard about. There's a reason hearsay isn't allowed in court testimony. By saying something like this, he really is spreading falsehoods and putting kids in danger. Plus, it just makes him appear stupid, especially when his claim is followed by, "I'm not arguing that vaccines are a bad idea, I think they're a good thing." Well, which is it?
