What are you looking for when you talk to this teacher? Make sure that you have a goal. Is it to get the teacher to admit they were wrong and apologize to the class? Stop tryng to push their own angry agenda? Get them fired? Make sure you know what it is that you want. (Make sure it is a realistic goal) Smile, be nice but firm, dress neatly, look like someone that should be taken seriously. Do not appear to be the same thing that teacher is, but Republican. I have been in Education for 27 yrs, am conservative, concealed carry, Pro-life, marriage=one man/one woman, strong military. Many of my colleagues feel the same way. The conservative teachers I know do not seem to push their beliefs off on their students, where a lot of the more liberal ones see it as part of their mission. When I first started 27 yrs ago every teacher I knew was a liberal (except my wife and I). There seems to be a lot more conservatives in the ranks now. Good Luck with your visit.
