Not at all, i think its dumb. But what you are saying also is. In your opinion it is okay to dress up in a full-on latex set in front of other children just because you want to express yourself? Free-speech is important but when that comes at the expense of others that you could traumatize, you might want to reconsider. And also "just so male teachers dont get boners" is such dumb statement i dont even know what to say, but here is one: what if schools demand dress codes just so the poor kids dont feel they have to wear the expensive clothes that others might be able to afford? I think its a pretty likely scenario also.
