Via Freedom Works:

I am currently in my freshman year of high school and the incidents are happening more frequently and I believe are more severe.  As you can imagine, the ongoing pressure and bullying has been disturbing to me, my friends and my family.

Just before the 2010 Midterm election, I was on the front page of the local newspaper for my political volunteer work and my teachers noticed. One of my seven teachers made it very clear that she dissaproved of my civic engagement. In a period of two months, my Geography teacher frequently would take me aside after school for a few minutes and tell me how stupid, wrong and misguided I was for being Republican. The harassment with this specific teacher got so bad, I had to switch schools halfway through the year.  At this time I was only 12 years old. To my knowledge, this teacher was not disciplined at all for her actions.
