You seem very unconcerned that people could be arrested for criticising religion, perhaps you are making my case for me.
First they came for the people who criticised religion ....
You know how that one goes, it was a rapid decline. Is it unfeasible that a slow creep to a place where liberty declines and authoritarianism increases, who knows where that could go, eventually.
A hate crime or incident could literally be anything. I remember a lady who went to see Frankie Boyle was upset at him making jokes about Down's syndrome as she had a child with the disorder. I suppose he could have been arrested, or at least interviewed over that.
A Hate Incident is any incident which the victim, or anyone else, thinks is based on someone’s prejudice towards them because of their race, religion, sexual orientation, disability or because they are transgender.
Dare you object to a bloke dressed as a woman using female facilities.
