See what I did there?
I'm an atheist, and could care less if you worship Christ or Tezcatlipoca, or if you say Merry Christmas or Happy Holidays, or if the Ten Commandments are displayed in a court. I do care however, when you try to impose YOUR religious views, your personal perception of morality, or whatever other "thing" must be true because you believe it; upon my personal rights and freedoms. If I were a woman, I don't want your views regulating my body. If I were gay, I don't want your views deprecating whom and how I should love someone. What a teacher chooses to wear or believe in is of no consequence to me, I do have an issue when said teacher tries to impose his or her beliefs onto my daughter, just as I would imagine you would have an issue if a muslim, or any other non-Christian person were to impose his beliefs onto your Christian children.
