Contentious Opinion Alert: It would serve the LGBT community well to call out members for stunts like this... These are the sort of antics that invite perfectly reasonable criticism.

So it went like this:
Middle school English teacher uses her power to conduct and experiment on her students by injecting politics into an assignment. When she dislikes the results she accuses them of hates-speech for voicing honest opinions which she solicited. That goes... Exactly as you would expect it to go when dealing with children and of course she then cries foul over completely predictable behavioral outcome. She's an adult and as such, should have known better than to stir the sh!t pot expecting it wouldn't spill over.
