content: I guarantee you know almost nothing about vaccination and its history, so why should anyone care about your opinion?  Why do you even have such a strong opinion?  Where did such ideas come from? People are so confused that they latch on to anything that they can "know" is true.  Being pro-vaccination seems so obviously correct that you amplify your feelings about the subject because this is one thing you can know you're right about.  But you don't actually know anything about vaccination, you just know what you've heard from people who lie to you about virtually everything.
