Everyone needs to be conscious about what they say and where they say it. But I certainly think it's problematic that I, as a job-seeking teacher, am not comfortable with publicly stating that I think marijuana should be legalized or that smoking a couple joints really isn't a big deal. I'm not even sure how comfortable I would be with posting on facebook that alcohol is significantly more dangerous than weed - even though that's just a factual statement and not my personal opinion.
I also think it's troublesome if other people feel a similar need to moderate themselves from making moderate statements questioning immigration policies. These are examples of hypersensitivity negatively shaping public discourse.
However, there is a far cry between moderate statements questioning immigration policies and statements I've actually seen have repercussions. I don't understand how a teacher can expect to teach muslims (and it's unlikely that European teachers, at least in cities, will have classes free of muslim students/pupils) while publicly stating that Islam represents evil and oppression. (The Norwegian leader of Pegida, who made such statements, lost his job because his pupils, understandably imo, had huge issues with him being supposed to teach them sociology).
At the same time, even though I don't think we're currently in a place where people have really unfairly lost their jobs for making 'politically incorrect' statements (most statement I've seen have job-repercussions has been of the 'let's beat up some shitniggers' type of racism, where I am actually completely fine with it having consequences), we must be cautious about how moderated public speech should be. This is not an easy debate, and attempting to draw a line is kind of a hopeless endeavor - certain statements are obviously not-ok and certain statements are obviously okay, but I can also think of many statements a teacher could possibly make where I would not be sure whether I'd be okay with it. Like, obviously we don't want mobs inciting violence towards minority groups - but we also don't want people to only publicly state opinions that coincide with majority opinion - then there is no longer room for debate. And while I don't really think we're at the point where 'slightly controversial, but should be okay' statements are all that negatively received (aside from the aforementioned drug case ), it's definitely important that we keep track of where we are going..
Not my quote, though I like it.
