I knew that homophobia leads to Neo-Nazism

So does the anti-vaxxer stuff. It starts with "I want my kids to be safe" then it's "I worry about the chemicals in vaccines" to "those dirty immigrants are bringing diseases" to "I'm a nazi now."

i dont think they understand how vaccines work, it is a surprisingly simple concept to grasp

For that matter, racism, anti-muslim/semitic/other minority bigotry, misogyny, classism and red-baiting all lead to the same place.
