Well the point is that we don't want people forcing religious views on a mainly secular society. If people have strong views on abortion, then they should abide by those views themselves, but we don't want them harassing people using legal health services. It's fine to protest about abortion etc, but not in a specific buffer zone which has been set up (via a PSPO) to protect vulnerable people visiting the clinic.

I don't know what you're on about with Halloween costumes - I can't see the relevance. Are there PSPOs designed to prevent scary costumes and has anyone been prosecuted for deliberately flouting the PSPO?
