What's the point?

I started to watch American Pie 2 the other night, on ITV2 I think. It started quite late, about 11:30pm I think, and I was watching it when I noticed things didn't seem quite right. I realised then that they had cut out all of the swear words.

I mean, surely only adults are watching at that time of night and it is up to them to decide whether they want to watch it, and secondly, a lot of the humour is smutty so I just figured there was no point continuing to watch it as who knows what else they had cut.
