Sorry, I completely fail to see what the issue is here.
A person has a political opinion contrary to your own, and so... what? You are scared of that? You think she should be stopped?
What does it make you if you think you have a right to criticize or demonize a person with different beliefs?
How about growing up and having a debate while respecting another person's opinions? Start discussion and maybe you'll learn something (and from a
teacher no less!

)
Personally, I think there is nothing but stigma here. Maybe you're afraid of what you might learn, maybe you're afraid of opening your mind to
various ideas instead of sticking with an accepted dogma because it might force you to question, and maybe you fear others would judge you for your
opinion?
Any political viewpoint (as in a label) is a generalized view, no person can ever agree with every tiny aspect one example propagates. There are
infinite views between all political ideals, and I don't believe people should simply follow labels as a popular movement.
Again, I don't get what the problem is here.
