I hate censorship of any kind and got some funny looks at bible study when I said I opposed banning porn sites.
I don't consider p@rn to be "speech". I completely disagree with that Supreme Court decision declaring that it is. The intent of the first amendment was to protect the ability of people to criticize their government, it was not conceived to be used for something like p@rn.
But if we have to keep it in order to protect actual "speech", I can live with it. I've seen some discussion of the idea of using p@rn sites to carry gun videos or other videos banned by Youtube.
