You are being incredibly disingenuous and missing out the very important points that ALL of those instances were designed to be provocative and make people feel in fear for their own safety.
e.g. the people being arrested for silent praying (wasn't it just two people?) were breaching specific PSPOs that are specifically designed to provide a safe buffer zone around abortion clinics so that people can receive their health services (i.e. abortion and related services) without fear of being harassed. By stating "silent praying", you make it look as thought they weren't being deliberately provocative in order to make a protest - the exact type of thing that the PSPO is designed to protect against.
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?
