Great news for anyone who wants to incite some hatred. The Criminal Justice and Immigration Act 2008 added a new offence of "Hatred on the grounds of sexual orientation".
However, according to Ministry of Justice guidance published on Tuesday, sexual orientiation "does not extend to orientation based on, for example, a preference for particular sexual acts or practices" so it "covers only groups of people who are gay, lesbian, bisexual or heterosexual."
What this seems to suggest is that you're free to persecute and hate people for being into personal scatological fetishes; freaky acts with AA batteries and willies; or people like Goatse who get their rocks off through personal and deliberate prolapse.
Bet that made your day huh?
Note: Do not search "Goatse" from a work machine.
