Student Access - Safeguarding or Censoring?

I posted a video on my principal blog yesterday. It's the music video of the Zimmers singing My Generation. (I like to put a variety of things on the site to keep staff and students interested.)

In the original version of the video (available on YouTube), the video ends with one of the singers giving the finger to the camera. It makes a point, and is actually the punchline of the video. After about an hour, I began to have a nagging thought, "was this appropriate material for a principal to post where students would see it"?

Being a high school, surely my students would NOT be offended by the gesture.

But is it appropriate for THE PRINCIPAL to post it??

I decided to edit the video by cutting it off just before the gesture. So if you were to look at my blog version, it's the G-Rated, rather than PG version of the video. But I must admit, I'm really uncomfortable enaging in ANY type of censoring of content that I post.

Am I wrong?

And precisely what is the role and responsibility of educators when it comes to allowing students access to the web?

What does your school or district do in this area?
