"The discrimination wasn't an isolated incident and it didn't just come from students," Smith writes. "When I told the principal that my civics teacher called me out in front of the whole class and said same-sex marriage was 'pretty much the same thing' as marrying a dog, the principal told me 'everybody has the right to their own opinion.' The next day, the teacher apologized, but as I walked away, he said 'don't go marrying your dog.'"
